Grey literature is a type of scientific information that is not formally published as articles in scholarly journals. It could be reports, dissertations, manuscripts, clinical guidelines produced by governments, universities and private companies.

An established definition of grey literature (am. gray literature) is as follows:

"[Grey literature is] that which is produced on all levels of government, academics, business and industry in print and electronic formats, but which is not controlled by commercial publishers, i.e., where publishing is not the primary activity of the producing body"

Joachim Schöpfel. Towards a Prague Definition of Grey Literature. Twelfth International Conference on Grey Literature: Transparency in Grey Literature. Grey Tech Approaches to High Tech Issues. Prague, 6-7 December 2010, Czech Republic. pp.11-26.

Scientific information usually defined as grey literature is for example:

Dissertations

Conference proceedings

Unpublished manuscripts

Recommendations and technical standards

Patents

Presentations

Government documents

Due to its diverse origins and unpublished nature, grey literature can be difficult to find. It is not, usually, indexed in regularly bibliographic databases.

Where do I find grey literature?

Searching Google is a good start. However, there are specific resources including grey literature, most of them free of charge. Several databases at Databases & e-resources do also include grey literature; for instance, dissertations are found in Cinahl and PsycInfo.

General resources

OpenGrey - European database including around 700,000 references: technical or research reports, doctoral dissertations, conference papers, official publications.

OAlster - Search enginge covering more than 1,500 resources including 30 million of documents. Hosted by OCLC.

Bielefeld Academic Search Engine (BASE) - One "of the world's most voluminous search engines especially for academic open access web resources", covering around 3,000 resources and more than 60 milllion documents, including several options for limits such as language, publication type and topic.

Health and medicine

Popline, produced by the Johns Hopkins Bloomberg School of Public Health, is a database of eproductive health literature. Besides scientific articles, you'll find unpublished documents in topics like demography, family planning, contraceptives, reproductive health, HIV/AIDS in developing countries and more. In "Advanced Search", you may limit the search to grey literature.

Via Global Index Medicus, you can search in several databases from the World Health Organization (WHO), for example LILACS and WHOLIS.

The New York Academy of Medicine is publishing a news letter, The Grey Literature Report in Public Health, alerting readers to new grey literature which are indexed, archived and made available through a search interface. [As of January 2017, the website is no longer updated.]

The Canadian Agency for Drugs and Technologies in Health (CADTH) has developed a comprehensive checklist named Grey Matters. The checklist has an international perspective and do, for example, list the Swedish Agency for Health Technology Assessment (SBU).

To find clinical trials, ClinicalTrials.gov is a good starting point. In addition, International Clinical Trials Registry Platform (ICTRP) by WHO aggregates several trials resources, among them also ClinicalTrials.gov.

Dissertations

DART-Europe - Search engine for European research theses from more than 570 universities in 28 countries.

Dissertations and Theses A&I - Comprehensive and commercial database (ProQuest) for dissertations and theses.

Knowing about some general search principles is important in order to get as good a result as possible. On this page you will learn more about how to structure your search in search blocks, find the balance between broad and narrow searches, combine search terms with boolean operators, search for word stems and phrases, use search fields and improve your searches.

Broad and narrow searches

When conducting a search, you want to find all the relevant articles and avoid all the irrelevant ones, which means that you have to find a balance between broad and narrow searches. A broad search will retrieve more documents, both relevant and irrelevant. The more alternative terms and synonyms each search block contains, the broader the search. A narrow search will retrieve fewer documents, both relevant and irrelevant ones. The more search blocks your search contains, the narrower the search.

Examples of broad and narrow searches

Broad search: (Feeding and eating disorders OR anorexia nervosa OR bulimia nervosa OR binge-eating disorder) AND (family-based treatment OR family treatment OR parent-therapist alliance OR parent-focused treatment OR parent-child relations OR parents OR home treatment)

Narrow search: Anorexia nervosa AND Family-based treatment AND Adolescents

Search blocks

When you are constructing your search strategy you need to organize the relevant terms you found into a structure. We recommend that you organize each part of your search into a search block which correspond to the different parts of your search query. In a simple search query in a database with a controlled vocabulary, a search block may consist of only one search term, but a search block may also consist of several variant terms and synonyms. In a database without a controlled vocabulary, such as Web of Science, synonyms and variant terms are often necessary in order for the search to be exhaustive and so as not to miss any relevant articles.

Example of search with two search blocks

Combining search words with Boolean operators (AND, OR and NOT)

With Boolean operators, you state how the search terms should be combined. The most commonly used Boolean operators in databases are AND, OR and NOT. They can be used in almost all databases. In certain databases, you can also use other, more specialised operators. You can find information about them in the help tet of each respective database.

Seach for documents containing all the search terms (AND)

AND means that all the search terms or search blocks you have combined need to be appear in the found documents: stroke AND depression retrieves documents which contain both stroke and depression. If you do not state how you want to combine your search words, many databases will try to interpret your question anyway. Usually the database will interpret your question as if the search words are combined with AND. The more terms you add with AND in between, the narrower your search will become. If you built your search with search blocks you should use AND between the search blocks.

Search for documents containing at least one of the search terms (OR)

OR means that at least one of the search terms needs to be found in the retrieved documents . You will get more hits for every word that you add combined with OR. Synonyms should be combined with an OR in between. For example, cancer can also be called neoplasms or tumours. A search for cancer OR neoplasms OR tumours, will find all three variants. OR is most needed in databases without a subject heading list. The more search terms you combine with OR in between, the broader your search will be. If your search blocks contain more than one search term you should use OR between the words belonging to the same block.

Search for documents not containing a specific term (NOT)

NOT limits the search by excluding documents that contain a certain term. If you search for animals NOT rats, you will find documents that contain the word animals but not the word rats. However, be careful with NOT because there is a risk that you will also exclude relevant material. Perhaps the word you exclude is only mentioned in the passing, or perhaps the authors even write that they have not studied that particular topic/aspect.

Using several Boolean operators in one search

If you use several different Boolean operators in your search, you must ensure that the database interprets the search in the way you want it to. The search Smoking AND cancer OR tumours OR neoplasms can give two different results depending on which search terms are linked together. One interpretation will result in documents that contain both smoking and tumours and documents that contain either of the words tumours or neoplasms. The other interpretation will result in documents that contain smoking together with one of the words cancer, tumours or neoplasms. This latter interpretation is probably the desired result of this search. There are different ways to clarify how your search is to be interpreted.

You can explicate how your search should be interpreted by:

Using brackets around the search words that are to be linked: smoking AND (cancer OR tumours OR neoplasms).

Writing the different search blocks in different search fields.

First performing a search for each block and then combining all the searches. Often this can be done under the "search history tab" where all individual searches have been saved.

Searching for part of words (truncation)

Truncation is used to search for different word endings or different variants of a word. In most databases you can search for parts of words by using truncation. In most databases, the symbol for truncation is the asterisk, *. Other symbols are also used and information about what symbol is used can be found in the help text of the database.

The most common way of using truncation is using the word stem, or the first part of a word. A search for therapy* will only find documents with that exact word, but not related terms such as for example therapies. But a search for the word stem therap* retrieves the terms therapy, therapies and therapeutical. Remember that too few letters before the truncation symbol can result in many irrelevant hits. If you search for ther*, you will not only get therapy, therapies, therapeutical; you will also get thermal and thermodynamic.

It is good to use truncation in free-text databases, for example Web of Science. In databases with a subject heading list, where search words are mapped to approved subject headings, you should be wary of using truncation. Sometimes truncation can knock out the databases mapping function and thos result in fewer hits.

Searching for phrases (quotation marks)

Sometimes it can be useful to search for phrases. Searching for phrases limits the search results and can make it easier for you to find relevant articles. In most databases, you search for a phrase by putting quotation marks around the phrase: "risk factor". With this search, you will only find articles where risk and factor are next to each other in the assigned order. You thereby exclude articles where risk and factor occur as two separated words. You can also truncate the phrase if necessary: "risk factor*", and then you will also find articles with the phrase "risk factors".

Phrase searching does not work together with subject heading mapping so avoid using quotation marks in databases like PubMed, CINAHL and PsycInfo.

Simple and advanced search forms

Many databases have more than one search form and offer several different ways of searching. Often it is possible to limit the search to a certain search field, for example, subject heading, title or author. Searching in all fields (sometimes called topic), is broader and often the best way to start. If you want to do a more specific search, you can restrict your search to one specific field. How the different search possibilities are presented varies from database to database, but often searching in all fields has been pre-selected, or is on the first page. The option to search in a specific field is often found in an advanced search form, or you are required to make a selection in a drop-down menu.

Improving your search

Perhaps you are not fully satisfied with the information you found after you performed a search? In that case, go through your search strategy and see if you can adjust it so as to gain a better search result. A more thorough check list to assess search strategies is the PRESS checklist (Peer Review of Electronic Search Strategies). The checklist is mainly used to assess searches for systematic reviews, but it might be useful for assessing other kinds of serch strategies as well.

Not enough hits?

Check the search logic. Have you used OR between synonyms and alternative terms which belong to the same search block? Have you written the different search blocks in different fields or put parentheses around the search blocks which contain more than one word?

Have you spelt things correctly? A spelling mistake may prevent the database from interpreting the word you have used.

Have you used several search blocks in your search? In that case you may consider removing one of the search blocks. Think about which search blocks are the most central to your search and do a search containing only those. There may not be many articles about your specific search question and in that case it can be a good idea to widen your search.

Try using broader search terms. In the subject headings lists like Mesh, the terms are hierarchically ordered and you can choose more general terms higher up in the hierarchy. The narrower terms will also be included in your search through the "explode" function.

Are there synonyms or alternative terms for some of your search terms? Add them, combined with OR. You can find synonyms and alternative terms in for example titles and abstracts of relevant articles.

Have you searched with subject headings? If you have been searching in Pubmed you should include Mesh terms in the search in order to be sure about finding everything written on a specific topic.

Have you used the advanced search form and limited your search to certain fields (like Title, Abstract or Mesh terms)? In that case, try to search in All Fields instead.

Have you been using filters in your search? Try to remove them. Maybe relevant articles have not been indexed in the way you would expect and in that case, you risk sorting them out by using filters.

Too many hits?

Did you really get to many hits? If you are going to do a more comprehensive assignment/essay you need to go through quite a long results list. How many articles you need to go through depends on the task at hand and the subject.

Check the search logic. Did you use AND between the search blocks? Check that you have written the different search blocks in different fields or put parentheses around the the search blocks that contain more than one term. If not, there is a risk that the search will retrieve a different result from the one you expected.

Is there any part in your search question that you have not included in the search? More search blocks in your search will retrieve fewer results.

Use narrower search terms. Can you replace any of your search terms with narrower terms? In subject heading lists such as Mesh the terms are hierarchically ordered, and you can see if there are any narrower terms lower down in the hierarchy.

If you have searched in all fields you can make the search more specific by only searching in a specific field. The most useful is to restrict your search to the subject headings field. Doing that you will avoid articles that only mention your search terms without actually dealing with the topic. You can also use more advanced functions such as subheadings and major topic.

Is there any filter in the database that is suitable for your topic, such as language, type of study, animal or human testing or age group?

Are you looking for scientific articles or writing references and need advice? You can get help from our librarians. We offer both drop-in via Zoom and booked consultations.

With Boolean operators, you state how the search terms should be combined. The most commonly used Boolean operators in databases are AND, OR and NOT. They can be used in almost all databases. In certain databases, you can also use other, more specialised operators. You can find information about them in the help tet of each respective database.

Seach for documents containing all the search terms (AND)

AND means that all the search terms or search blocks you have combined need to be appear in the found documents: stroke AND depression retrieves documents which contain both stroke and depression. If you do not state how you want to combine your search words, many databases will try to interpret your question anyway. Usually the database will interpret your question as if the search words are combined with AND. The more terms you add with AND in between, the narrower your search will become. If you built your search with search blocks you should use AND between the search blocks.

Search for documents containing at least one of the search terms (OR)

OR means that at least one of the search terms needs to be found in the retrieved documents . You will get more hits for every word that you add combined with OR. Synonyms should be combined with an OR in between. For example, cancer can also be called neoplasms or tumours. A search for cancer OR neoplasms OR tumours, will find all three variants. OR is most needed in databases without a subject heading list. The more search terms you combine with OR in between, the broader your search will be. If your search blocks contain more than one search term you should use OR between the words belonging to the same block.

Search for documents not containing a specific term (NOT)

NOT limits the search by excluding documents that contain a certain term. If you search for animals NOT rats, you will find documents that contain the word animals but not the word rats. However, be careful with NOT because there is a risk that you will also exclude relevant material. Perhaps the word you exclude is only mentioned in the passing, or perhaps the authors even write that they have not studied that particular topic/aspect.

Using several Boolean operators in one search

If you use several different Boolean operators in your search, you must ensure that the database interprets the search in the way you want it to. The search Smoking AND cancer OR tumours OR neoplasms can give two different results depending on which search terms are linked together. One interpretation will result in documents that contain both smoking and tumours and documents that contain either of the words tumours or neoplasms. The other interpretation will result in documents that contain smoking together with one of the words cancer, tumours or neoplasms. This latter interpretation is probably the desired result of this search. There are different ways to clarify how your search is to be interpreted.

You can explicate how your search should be interpreted by:

Using brackets around the search words that are to be linked: smoking AND (cancer OR tumours OR neoplasms).

Writing the different search blocks in different search fields.

First performing a search for each block and then combining all the searches. Often this can be done under the "search history tab" where all individual searches have been saved.

Searching for part of words (truncation)

Truncation is used to search for different word endings or different variants of a word. In most databases you can search for parts of words by using truncation. In most databases, the symbol for truncation is the asterisk, *. Other symbols are also used and information about what symbol is used can be found in the help text of the database.

The most common way of using truncation is using the word stem, or the first part of a word. A search for therapy* will only find documents with that exact word, but not related terms such as for example therapies. But a search for the word stem therap* retrieves the terms therapy, therapies and therapeutical. Remember that too few letters before the truncation symbol can result in many irrelevant hits. If you search for ther*, you will not only get therapy, therapies, therapeutical; you will also get thermal and thermodynamic.

It is good to use truncation in free-text databases, for example Web of Science. In databases with a subject heading list, where search words are mapped to approved subject headings, you should be wary of using truncation. Sometimes truncation can knock out the databases mapping function and thos result in fewer hits.

Searching for phrases (quotation marks)

Sometimes it can be useful to search for phrases. Searching for phrases limits the search results and can make it easier for you to find relevant articles. In most databases, you search for a phrase by putting quotation marks around the phrase: "risk factor". With this search, you will only find articles where risk and factor are next to each other in the assigned order. You thereby exclude articles where risk and factor occur as two separated words. You can also truncate the phrase if necessary: "risk factor*", and then you will also find articles with the phrase "risk factors".

Phrase searching does not work together with subject heading mapping so avoid using quotation marks in databases like PubMed, CINAHL and PsycInfo.

Simple and advanced search forms

Many databases have more than one search form and offer several different ways of searching. Often it is possible to limit the search to a certain search field, for example, subject heading, title or author. Searching in all fields (sometimes called topic), is broader and often the best way to start. If you want to do a more specific search, you can restrict your search to one specific field. How the different search possibilities are presented varies from database to database, but often searching in all fields has been pre-selected, or is on the first page. The option to search in a specific field is often found in an advanced search form, or you are required to make a selection in a drop-down menu.

Improving your search

Perhaps you are not fully satisfied with the information you found after you performed a search? In that case, go through your search strategy and see if you can adjust it so as to gain a better search result. A more thorough check list to assess search strategies is the PRESS checklist (Peer Review of Electronic Search Strategies). The checklist is mainly used to assess searches for systematic reviews, but it might be useful for assessing other kinds of serch strategies as well.

Not enough hits?

Check the search logic. Have you used OR between synonyms and alternative terms which belong to the same search block? Have you written the different search blocks in different fields or put parentheses around the search blocks which contain more than one word?

Have you spelt things correctly? A spelling mistake may prevent the database from interpreting the word you have used.

Have you used several search blocks in your search? In that case you may consider removing one of the search blocks. Think about which search blocks are the most central to your search and do a search containing only those. There may not be many articles about your specific search question and in that case it can be a good idea to widen your search.

Try using broader search terms. In the subject headings lists like Mesh, the terms are hierarchically ordered and you can choose more general terms higher up in the hierarchy. The narrower terms will also be included in your search through the "explode" function.

Are there synonyms or alternative terms for some of your search terms? Add them, combined with OR. You can find synonyms and alternative terms in for example titles and abstracts of relevant articles.

Have you searched with subject headings? If you have been searching in Pubmed you should include Mesh terms in the search in order to be sure about finding everything written on a specific topic.

Have you used the advanced search form and limited your search to certain fields (like Title, Abstract or Mesh terms)? In that case, try to search in All Fields instead.

Have you been using filters in your search? Try to remove them. Maybe relevant articles have not been indexed in the way you would expect and in that case, you risk sorting them out by using filters.

Too many hits?

Did you really get to many hits? If you are going to do a more comprehensive assignment/essay you need to go through quite a long results list. How many articles you need to go through depends on the task at hand and the subject.

Check the search logic. Did you use AND between the search blocks? Check that you have written the different search blocks in different fields or put parentheses around the the search blocks that contain more than one term. If not, there is a risk that the search will retrieve a different result from the one you expected.

Is there any part in your search question that you have not included in the search? More search blocks in your search will retrieve fewer results.

Use narrower search terms. Can you replace any of your search terms with narrower terms? In subject heading lists such as Mesh the terms are hierarchically ordered, and you can see if there are any narrower terms lower down in the hierarchy.

If you have searched in all fields you can make the search more specific by only searching in a specific field. The most useful is to restrict your search to the subject headings field. Doing that you will avoid articles that only mention your search terms without actually dealing with the topic. You can also use more advanced functions such as subheadings and major topic.

Is there any filter in the database that is suitable for your topic, such as language, type of study, animal or human testing or age group?

Turning your research question into a search strategy

# data[].attributes.attachment_link.readable_text
In this this three-minute video tutorial, we share some useful Scopus search tips to make your research more effective. Watch the video here.

First, it's important to know that the data in Scopus is highly structured; every piece of information is tagged, even down to the initials of the author inside an article's list of references. This is what ensures that your search will be precise and return reliable results and is also what differentiates Scopus from web search engines.

Here are 6 key things to keep in mind when searching in Scopus:

1. Loose phrases vs. separate words

One of the most important things to remember, and easiest to misunderstand, is searching phrases. If you do not specify anything between two words, Scopus automatically joins them with AND, so the words in the phrase may not be searched together. You'll get more results, but that maybe what you were looking for.

TIP: To search for a phrase in Scopus use double quotations marks ("). Doing so tells Scopus this is a "loose phrase," meaning that the words must be together and will allow for wildcards and lemmatization (finding both singular and plural forms, see below).

Example: "conversion disorder"

Enter conversion disorder in the search form and Scopus interprets it as 'conversion' and 'disorder.' You results could find documents relating to both "disorders of vision" and "image conversion".

Whereas, when you enter "conversion disorder" (with the double quotations) Scopus looks specifically for the words 'conversion' and 'disorder' to be together in the fields you are searching.

The results received from this search ran on February 17, 2022: Without quotations = 15,209 items; With double quotations = 3,946 items.

2. TITLE-ABS-KEY is the default search field

Why? Because Scopus is an Abstract and Indexing database, meaning it provides you with key information and metrics for scholarly literature across 7,000 publishers, but it does not contain the full-text. Following standard science conventions, these three fields contain the most relevant information and provide the best starting point:

TITLE: Should contain the most relevant terms to the literature

ABS: The article abstract should be a condensed summary of the full-text

KEY: Author keywords express what authors or journal editors consider to be important keys to the article content. Indexing vocabulary terms from subject-specific databases like EMBASE, MedLine and Compendex are also included in the Keyword search.

If you are looking for a topic covered by a specific author, source, affiliation, etc. you can choose to restrict your search to a specific field, or add another search using <Add search field>.

3. Know what Scopus search does automatically. Use curly brackets { } if you want to search for an exact phrase:

Accented characters: work with or without the accent included

Example: Dvořák and Dvorak both return the same results

Lemmatization: (similar but not quite the same as truncation or stemming) means that singular and plural forms, and well as adjectives, will be found if you type any of the variants. You can override this behavior by using the EXACT PHRASE marker-accolades or curly brackets-which will give an exact match of what you type (this does not apply to accented characters). See bulleted point below.

Examples: attack and attacks; wide and wider

Equivalents: will find the equivalent terms/symbols

Examples: ω and omega; behaviour and behavior

Punctuation: Commas, hyphens,?, ! etc., are ignored

Stop words: Words like "the," "it," and "of" are excluded from search (Refer to the list found in Scopus help)

Override with Exact phrase: { } will find only an exact match for a word, phrase or character (including stop words)

4. Use proximity operators to find words near one another

By including proximity operators in your search, you may find articles you might otherwise miss. There are two proximity operators you can use:

Preceding (Pre/n): The first word must be no more that (n) words apart from the second word

Within (W/n): It doesn't matter which word comes before the other

Example for Pre/n: You are searching for content related to zika virus. You could do a loose phrase search ("zika virus"), which is a good start, but you might miss literature that talks about 'zika and dengue virus.'

Instead, try to enter your search using: Pre/n: zika Pre/2 virus

This will find literature where 'zika' precedes 'virus' within 2 words, such as both "zika virus" and "zika and dengue virus"

Example for W/n: Enter your search using the within operator, for example: zika W/2 virus

This would look for 'virus infection with zika,' 'Virus like zika,' 'virus, zika,' 'zika virus,' etc.

5. Wildcards

In any word or "loose phrase" you can use wildcards to help when you're unsure of spelling, or when a word has multiple spelling variations, or if you're looking for chemicals. There are two wildcard types, ? and *.

? represents any single character

Example: wom?n retrieves both woman and women

* represents any number of characters, even zero

comput* returns computer, computers, computerize and computerization

*tocopherol finds α-tocopherol, γ-tocopherol , δ-tocopherol, tocopherol, etc.

6. The Scopus help files are your friend

As you build your search, you can always refer to the " search tips " button in the top left corner of the search form (or use the 'Help' button in the top navigation bar) to access helpful information on search syntax and access tutorials.

Você já ouviu falar em fontes de informação?

Fontes de informação são essenciais no estudo e na pesquisa acadêmica. São nelas que você encontra informações relevantes para desenvolver seu trabalho.

É imprescindível que você conheça as principais fontes da sua área de atuação, saiba localizar informações e dados confiáveis.

Então, se você não sabe o que são fontes de informação ou se fica perdido sem saber onde pesquisar, leia este post até o final!

O QUE SÃO FONTES DE INFORMAÇÃO?

Fontes de informação são todas as publicações, ferramentas e recursos que disponibilizam informação a pessoa que dela necessita. É o local onde você encontrará a informação que procura. Um periódico científico, por exemplo, é uma fonte de informação da mesma forma que uma base de dados ou um catálogo de bibliotecas.

As fontes de informação podem estar disponíveis de forma impressa (enciclopédias, dicionários, livros, etc.) e/ou digital (bases de dados, repositórios, mecanismos de busca, etc.).

Também podem ser categorizadas como formais (publicações de editoras, periódicos científicos, etc) e informais (comunicações, contatos pessoais, mensagens eletrônicas e outros).

TIPOS DE FONTES DE INFORMAÇÃO

As fontes de informação podem ser classificadas de diversas formas. A tipologia mais conhecida no meio acadêmico é: fontes primárias, secundárias e terciárias.

Fontes de informação primárias

Fontes de informação primárias são as publicações originais, o documento propriamente dito, a literatura escrita pelo autor, sem interferência e análise de outros meios.

Normalmente, serão as fontes primárias que você utilizará na leitura e no embasamento de sua pesquisa e/ou trabalho acadêmico:

Periódicos científicos

Tese

Dissertação

Anais de congresso

Trabalho de evento

Normas técnicas

Patentes

Entrevista

História oral

Relatório, etc.

Fontes de informação secundárias

Fontes de informação secundárias são aquelas que contêm as fontes primárias. Elas organizam e facilitam o acesso à literatura primária. Também são fontes secundárias análises, interpretações, resumos e sínteses das fontes primárias.

Você utilizará muito as fontes de informação secundárias para encontrar artigos, trabalhos de eventos e outras publicações relevantes para sua pesquisa ou trabalho acadêmico.

Exemplos:

Fontes de informação terciárias

Fontes de informação terciárias são as que compilam e remetem às fontes secundárias e primárias, indicando e organizando-as para facilitar o acesso.

Exemplo:

Diretórios

Portais

Mecanismos de busca (Google, BING, etc.)

Catálogos coletivos

Bibliografias

Centros de informação

Bibliotecas

Revisões de literatura

Serviços de indexação e resumo.

USO DAS FONTES DE INFORMAÇÃO

Dependendo da sua necessidade de informação, você fará uso de diferentes tipos de fontes de informação.

Aqui, listamos algumas sugestões e possibilidades, não é uma lista exaustiva e definitiva.

Nada impede que você utilize as fontes de informação conforme a sua necessidade.

COMO IDENTIFICAR SE UMA FONTE DE INFORMAÇÃO É CONFIÁVEL?

Com a quantidade de informação disponível na Web e com a desinformação em alta, é necessário saber identificar se uma fonte de informação é confiável ou não, principalmente as fontes disponíveis na internet.

Confira alguns critérios importantes para a identificação de fontes de informação relevantes e confiáveis para sua pesquisa acadêmica:

Autoridade

Pode-se identificar a qualidade da fonte de informação pela reputação do autor e/ou instituição. É aconselhável pesquisar conteúdos e publicações provenientes de instituições de renome na sua área de atuação, tais como: sociedades científicas, conselhos, etc.

Ao buscar conteúdos e publicações em mecanismos de busca, selecione os de autoria de pesquisadores reconhecidos na sua área. Escolha artigos de periódicos científicos que tenham revisão por pares e/ou sejam publicados por editoras ou sociedades científicas reconhecidas nacional e/ou internacionalmente.

Caso você queira usar informações disponíveis em sites ou blogs, verifique se há informações suficientes sobre a instituição responsável (sobre nós, missão, visão, contato, etc.) que possa confirmar a autoridade no assunto.

Atualidade

A atualidade é um critério que deve levar em conta a área do conhecimento. Em algumas áreas há uma rápida atualização do conhecimento enquanto em outras as informações permanecem válidas por muitos anos devido à natureza da própria área.

Apesar da atualidade variar conforme a área, é aconselhável pesquisar conteúdos novos e identificar fontes de informação que estejam sendo constantemente atualizadas. Fontes de informação, tais como sites, com datas de publicações muito antigas e que apresentem links quebrados devem ser muito bem analisadas antes de se optar pelo seu uso.

Precisão e objetividade

Precisão e objetividade estão relacionados à informação exata, sem erros de ortografia ou de conteúdo. A fonte de informação deve apresentar um texto bem escrito, claro e objetivo, que facilite a leitura, compreensão e interpretação.

Ela também precisa ser imparcial, apresentar fatos consistentes e verdadeiros.

Caso você acesse uma fonte de informação digital e encontre erros básicos, confira a autoridade do autor ou instituição. Não é recomendável o uso de fontes de informação que apresentem algum tipo de inconsistência.

Enfim, as fontes de informação irão te acompanhar durante o percurso da graduação e da pós-graduação, ainda mais se você optar por seguir a carreira acadêmica. Por isso, é importante você já se familiarizar com elas, descobrir quais fornecem informações relevantes e confiáveis na temática em que pretende trabalhar.

# data[].attributes.body
Para definirmos um bom critério de elegibilidade devemos resgatar nossa pergunta de revisão, objetivos e pensar quais elementos precisam estar presentes!

Alguns exemplos: tipo de metodologia aplicada; população do estudo, local...

Já em relação aos critérios de exclusão, estes não podem ser exclusivamente a negação de tudo o que não estiver nos critérios de elegibilidade, mas sim especificar o que será excluído e por quais motivos.
