I visited this server a year or two ago and tbqh I think it's more about the library building (a very large and impressive build) then the contents of the library. The library building so so huge you can spend several minutes walking from one book to the other. If it were just about distributing the books through minecraft they could have created a much more compact library where all the books are within convenient reaching distance.

Basically it's more of an art installation than it is a serious censorship circumvention tool. Still neat for what it is I guess.
