Could you explain more exactly what "library genesis" is? Is it a collection of basically every book ever published or only modern things? Did someone scan everything, like Google books?
It's basically a huge collection of documents, mostly scientific with a FOSS codebase for serving. It comes with metadata. It is mirrored a lot thanks to bring completely open. It originated in Russia and has had quite the history. It is a great step into the direction how documents (especially scientific) should be available to anyone in bulk without restrictions.
