Library Genesis is a Russian project to create a free online library of ebooks. They currently have about 4 million of them. The project is in blatant violation of copyright, and their domain name is blocked in some countries.
History
To explain the mess around multiple mirrors and forks this text was stolen researched from AA[1]
The quick story of the different Library Genesis (or “Libgen”) forks, is that over time, the different people involved with Library Genesis had a falling out, and went their separate ways.
- The “.fun” version was created by the original founder. It is being revamped in favor of a new, more distributed version.
- The “.rs” version has very similar data, and most consistently releases their collection in bulk torrents. It is roughly split into a “fiction” and a “non-fiction” section. Originally at “http://gen.lib.rus.ec”.
- The “.li” version has a massive collection of comics, as well as other content, that is not (yet) available for bulk download through torrents. It does have a separate torrent collection of fiction books, and it contains the metadata of Sci-Hub in its database. According to this forum post, Libgen.li was originally hosted at “http://free-books.dontexist.com”.
- Z-Library in some sense is also a fork of Library Genesis, though they used a different name for their project.

Torrent structure
Non-fiction torrents
Each torrent contains at most 1000 files, filename of each file is its MD5 checksum in lower case (see also article[IA•Wcite•.today•MemWeb] par. 23 for internals description). Internal LibgenID integer number of the book is used to determine torrent file, e.g. file with LibgenID=1234567 belongs to r_1234000.torrent, torrents start at round thousands so far. Some files can be excluded from the generated torrents for various reasons, when it happens the torrent will contain less than a 1000 files.
Scimag torrents
Each torrent contains 100 ZIP files, each with 1000 PDFs distributed in directories by their DOI prefix, like:

Internet Archive has darked (hidden/unindexed) collections.
- scimag: up to 64000000-64099999
- foreignfiction: up to 1600000
- libgen: up to 2092000
