gen lib rus ec is a high-tech, free-to-use file sharing web site for sharing academic, research, and general-interest media such as textbooks, ebooks, images, comics and music. The site allows free online access to material that otherwise may not be digitized or paywalled elsewhere. This is possible because the site's server is leased by a commercial company, allowing users to create a library of their own. It also allows them to post comments and reviews about the content and make donations. It is also possible to subscribe to a specialized feeds that bring the latest articles directly to you.

Many scientific articles are available to members and while many people may find these hard to read due to the size of the PDF files, there are a number of PDF mirror sites on the Internet that provide the same content with higher quality and fewer file sizes. These mirrors include the Science eBook Library, an archive of over one million of scientific articles. In addition, there are library genesis mirrors that are specific to journals and textbooks including the Chemistry Science eBook Library, which contains over twenty thousand peer reviewed journal articles.

Scientists have used the technology of the Internet and its associated technologies for years to make their work more accessible to the general public. But until Library genesis, many scholars did not have easy and affordable ways to obtain, read, and use their scientific articles. Fortunately, due to the work of volunteers and generous donors, the software and infrastructure required to maintain a digital archive has been developed and now exists on servers maintained by over a dozen free and low cost websites. These sites continue to improve on the services offered to the general public by adding new materials and expanding upon the best features of the older free epub Serengeti ePub repository.
