Editor’s note: This search tool is part of The Atlantic’s investigation into the Library Genesis data set. You can read an analysis about LibGen and its contents here. Find The Atlantic’s search tool for movie and television writing used to train AI here.

Disclaimer: LibGen contains errors. You may, for example, find books that list incorrect authors. This search tool is meant to reflect material that could be used to train AI programs, and that includes material containing mistakes and inaccuracies.

It’s impossible to know exactly which parts of LibGen Meta used to train its AI, and which parts it might have decided to exclude; this snapshot was taken in January 2025, after Meta is known to have accessed the database, so some titles here would not have been available to download.
