About Sci-Hub

A research paper is a special publication written by scientists to be read by other researchers. Papers are primary sources necessary for research – for example, they contain detailed description of new results and experiments.

papers in Sci-Hub library: more than 87,977,763

At this time the widest possible distribution of research papers, as well as of other scientific or educational sources, is artificially restricted by copyright laws. Such laws effectively slow down the development of science in human society. The Sci-Hub project, running from 5th September 2011, is challenging the status quo. At the moment, Sci-Hub provides access to hundreds of thousands research papers every day, effectively bypassing any paywalls and restrictions.

Sci-Hub Ideas

Knowledge to all

We fight inequality in knowledge access across the world. The scientific knowledge should be available for every person regardless of their income, social status, geographical location and etc.

Our mission is to remove any barrier which impeding the widest possible distribution of knowledge in human society!

No Copyright

We advocate for cancellation of intellectual property, or copyright laws, for scientific and educational resources.

Copyright laws render the operation of most online libraries illegal. Hence many people are deprived from knowledge, while at the same time allowing rightholders to have a huge benefits from this. The copyright fosters increase of both informational and economical inequality.

Open Access

The Sci-Hub project supports Open Access movement in science. Research should be published in open access, i.e. be free to read.

The Open Access is a new and advanced form of scientific communication, which is going to replace outdated subscription models. We stand against unfair gain that publishers collect by creating limits to knowledge distribution.
