The full name of CPSR is Inter-university Consortium for Political and Social Research, which translates into Chinese as a consortium of political and social research universities. It is one of the most important academic research databases in the world. Including educational, social, economic, demographic, historical and other research materials, there are a total of Social Sciences and behavioral sciences, including basic and applied information, which allows about 9,000 research topics and 500,000 archives. It covers 16 areas, such as education, ageing, criminal justice, terrorism and so on. It is very suitable for students of humanities. Although it is the academic resource bank of the United States, our classmates in the United Kingdom can also use it through the Internet. It should be noted that ICPSR adopts membership system, through which one part of the information is public, anyone can read, download and use it; the other part is that only members can use it. ICPSR currently has more than 700 member institutions, including universities and research centers.

The first one to introduce to you is Google Scholar (Google Academic Search), a free online search engine for academic articles, developed by computer expert Anurag Acharya. It can help users find academic documents including journal papers, dissertations, books, preprints, abstracts and technical reports, covering natural science, humanities, Social Sciences and other disciplines. The BETA edition was released in November 2004 and contains peer-review articles by the largest academic publishers in Europe and the Americas, which are largely ignored in general search engines. In addition to the excellent academic search done by Google Scholar, there is also a super useful gadget called "Google Alert". It's very simple to use. Once you open the Alert function, just enter the key words related to your research into Google Alert, and then, as long as you have the similar or similar information in the title or summary of the new article, Google Scholar will be able to use it. Send an email to your email address to remind you of "you get some papers to read!" For those who want to do a literature review, look for a large number of relevant academic resources.
