Z-Library (abbreviated as z-lib, formerly BookFinder) is a shadow library project for file-sharing access to scholarly journal articles, academic texts and general-interest books. It originated as a mirror of Library Genesis, and most of its books are from Library Genesis. However, some of them are uploaded directly to its site by individuals, and are not included in the collection held by Library Genesis.[3] Individuals can also contribute to the website's repository to make literature accessible to as many people as possible.[4]
