Online Research Papers For Free
Until the end of 2014, Sci-Hub relied on Lib Gen as storage: papers requested by users were requested from Lib Gen and served from there if available, otherwise they were fetched by other means and then stored on Lib Gen.
A 2019 study of 27.8 million download requests via Sci-Hub indicates that 23.2 million of these were for journal articles, 4.7 million (22%) of which were articles from medical journals.
The Sci-Hub website provides access to articles from almost all academic publishers, including Elsevier, Springer/Nature, Institute of Electrical and Electronics Engineers, American Chemical Society, Wiley Blackwell, and The Royal Society of Chemistry, as well as open-access works, and distributes them in violation of publishers' copyrights.
Users can access works from all sources with a unified interface, including by: entering the DOI in the search bar on the main page or in the Sci-Hub URL (like some academic link resolvers); or appending the Sci-Hub domain to the domain of a publisher's URL (like some academic proxies).
If the paper is in the repository already, the request is served immediately.
If the paper is not already in the repository, a wait screen appears while the site presents someone else's credentials on behalf of the user to a series of proxies until it finds one that has access to the paper, which is then presented to the user and stored in the repository.
For embargoed deposits, some institutional repositories have a copy-request button (e.g., DSPACE, EPrints).Back in 2010, we shared with you 100 awesome search engines and research resources in our post: 100 Time-Saving Search Engines for Serious Scholars.It’s been an incredible resource, but now, it’s time for an update.Check out our new, up-to-date collection to discover the very best search engine for finding the academic results you’re looking for.Resources like the Library of Congress have considerable archives and documents available, and many of them have taken their collections online.Science Huβ is a global science and technology publisher and provides free access to research articles and latest research information without any barrier to scientific community.Our internationally recognized publishing program covers wide array of science and technology disciplines.In November 2018, Russia's Federal Service for Supervision of Communications, Information Technology and Mass Media has blocked Sci-Hub and its mirror websites after a Moscow City Court ruling to comply with Elsevier's and Springer Nature's complaints regarding intellectual property infringement.According to The Scholarly Kitchen, a blog established by the Society for Scholarly Publishing whose members are involved in legal action against Sci-Hub, credentials used by Sci-Hub to access paywalled articles are correlated to access of other information on university networks and credential sales in black markets.Other methods used for requesting papers include inquiry by direct email to paper authors or other academics or by requesting them via online research forums or social networks, like the #ICan Haz PDF Twitter tag.Another way to provide users with access to pay-walled papers is through "green" open access self-archiving, in which the authors of the articles deposit them in their institutional repositories.
