Archival Status

The Library Genesis Seeding Project [12] is a group effort on Reddit with The-Eye.eu that aims to seed the entire Library Genesis non-fiction collection. Users are actively being recruited to help preserve the library by seeding any parts of the torrent collection they can (each torrent containing 1,000 books is about 10 GB).

Internet Archive has darked (hidden/unindexed) collections.
