> Z-Library is a popular (and illegal) library. They have taken the Library Genesis collection and made it easily searchable. On top of that, they have become very effective at soliciting new book contributions, by incentivizing contributing users with various perks. They currently do not contribute these new books back to Library Genesis. And unlike Library Genesis, they do not make their collection easily mirrorable, which prevents wide preservation. This is important to their business model, since they charge money for accessing their collection in bulk (more than 10 books per day).
