Google web application for searching academic articles for free. In June 2004, 165438+ 10, Google released the trial version of Google Academic Search for the first time. This index includes most of the published academic journals in the world, and can be widely searched for academic literature.
3. The origin of the library
The website is:
1.http://gen.lib.rus.ec/
2.http://libgen.io/
Library Genesis claims to be a plan to help all mankind spread knowledge, without copyright. There are many papers on the website, which are easy to download, as well as many foreign language books and Chinese books, which are updated almost every day. This is also a magical website. Basically all foreign books and papers can be searched and downloaded, and recent academic papers can also be downloaded.
Library Genesis and Sci-Hub are brothers in trouble. Before, both of them were in dispute because of Elsevier, and things that can't be downloaded from Library Genesis can also be downloaded directly from the webpage to Sci-Hub.
4.PMC University
http://www.ncbi.nlm.nih.gov/pmc/
The Center for Public Medicine (PMC) is a service provided by the National Institutes of Health, which archives biomedical and life science research documents. PMC is authorized by NLM(National Library of Medicine) to collect and archive biomedical and medical literature, and free of charge is the core principle of PMC.
With the development of technology, the current digital storage format of literature may be eliminated, but PMC keeps these contents permanently. NLM believes that digital data is not for storage, but the best use is continuous application, so free of charge is a core principle of PMC.
5. Book series
The book series website is rich in books, and basic professional books can be found for free download. Including gaming companies, Bookzz, Bookfi, etc. , you can download documents and books for free. Document download is suitable for previous years, needless to say, there are so many books!
Among them, BookSC website (http://zh.booksc.org/) has many documents. Up to today, BookSC has more than 2.78 million books and 52.42 million documents for free download, most of which are in PDF, Djvu and EUPB formats.
The above is Bian Xiao's sharing of academic literature websites. In a word, these websites are very useful in thesis writing, and I hope to help the graduating friends in thesis writing. For more related content, welcome to pay attention to this platform!
