In addition, several methods of searching foreign literature are summarized and shared with you. If you have a better search method, please add it.
I. x-mol
Search x-mol directly in Baidu, and you can find many documents here, many of which can be downloaded directly. Even if you can't download it, you can still see its doi and copy it to Baidu Academic, Google Search, sci-hub, and web of science. The basic idea is to find the doi of the literature and download it.
Second, always have keywords.
If you already have the literature keywords you are looking for, you can go directly to Google Academic, sci-hub, ProQuest and other websites for direct search.
Third, pay attention to foreign universities.
Finally, you can also pay attention to the doctoral dissertations of foreign comprehensive universities, such as Princeton, Yale, MIT, Stanford, Berkeley (California) and so on. However, when translating master's and doctor's papers, because the length of master's and doctor's papers is too long, everyone must do a good job in reading the papers, otherwise it may take a long time to translate an article, but the result is counterproductive.
