Sci-Hub is the most controversial project in modern science. The goal of Sci-Hub is to provide free and unrestricted access to all scientific knowledge.

Sci-Hub started as a tool for providing quick access to articles from scientific journals - such articles are the main medium of communication of scientific knowledge today. Now Sci-Hub has grown a database of 88,343,822 research articles and books - freely accessible for anyone to read and download.
Previously this knowledge was only available for high prices that most people cannot pay. Sci-Hub has revolutionized science by making all paid knowledge free.
Millions of people all over the world use Sci-Hub to unlock access to knowledge. They come from all countries and not only the poorest ones. Many Sci-Hub users come from USA and Europe. For more detailed stats, visit the statistics section.

Sci-Hub is extremely popular among scientists. Students use Sci-Hub for their research projects and graduation theses that are available here.

Sci-Hub also helps journalists, startups, and everyone who loves to learn new things.

Many medical professionals rely on Sci-Hub, because a great chunk of scientific journals are journals about medicine.

Sci-Hub helps to diagnose illnesses and prescribe therapy: free access to information saves human lives. More information about medical usage of Sci-Hub is available here.

Sci-Hub is a part of the Open Access Movement in science. The movement emerged in 1990s as a reaction to increasingly growing prices for academic journals: university libraries could not afford journal subscriptions. Librarians and researchers argued for making access to knowledge free or cheap.

High prices are unjustified and were made possible by monopoly-like mechanisms in academic publishing. The most appalling fact: the authors of articles in academic journals receive zero money for their work.

Sci-Hub became the most radical - and so far the most succesful - take on the open access.
