Popular shadow library LibGen continues to face trouble. In addition to ongoing technical problems, a U.S. lawsuit resulted in several domain suspensions and seizures in recent weeks. To top it off, the shadow library was just added to Germany’s pirate site blocking list, making it harder to access the remaining domains.
There should be all of LibGen corpus pinned on IPFS and there used to be a front end hosted on IPFS but I have not looked at it in a while.
