When .is is under DDoS attack or court pressure, the admins rotate to libgen.st.

Anna’s Archive (annas-archive.org) is the most important development in shadow libraries since Sci-Hub. It is not a library itself but a search engine that aggregates metadata from LibGen, Z-Library, Sci-Hub, and the Internet Archive.

Before diving into alternatives, it is crucial to understand why you need one. The original LibGen project operates from multiple jurisdictions (primarily Russia and the Netherlands) to dodge copyright injunctions. The specific subdomain gen.lib.rus.ec was historically the main search portal, but it has become a legal target.

Consequently, using the old URL is frustrating. You need a current, stable alternative.

While not a direct "alternative," Sci-Hub (current working domains: sci-hub.se, sci-hub.st) was born from the same ecosystem. Sci-Hub specializes in journal articles, while LibGen focuses on books. If you need a specific DOI (Digital Object Identifier), Sci-Hub is superior.

Libgen.li offers a completely different user interface that many find more modern than the classic LibGen look.
