Hurry up with downloading these from the website because the Flibusta author has reported on having glioblastoma few days ago, and there is no new leader for the project. The servers are going to be shut down and the good name is going to be spotless because of not reused. Probably this is why you told about "two great libraries of humanity dying at the same time". BTW all 450Gb of Flibusta can be downloaded via torrents but I don't know how to download all of Libgen.
