z-library.sk is a massive, controversial "shadow library" offering free downloads of millions of e-books and academic articles, operating largely outside copyright laws, aiming to provide universal access to knowledge but facing legal shutdowns and operating through various domains (like z-lib.id, z-lib.ai) and even private membership options after U.S. takedowns. It originated as a spin-off of Library Genesis (LibGen), and hosts pirated content, resulting in bans and legal issues from publishers; however, it remains popular for its vast, free collection.
