One of the interesting features of LibraryThing is all the statistics.
Currently there are slightly over 74,000 users with a total library of slightly over 5,248,000 books (1,200,000 unique). It might not be a good random sample. But the list of the top 25 most popular books is interesting. (The first 7 aren’t too surprising. #7 will drop to #8, likely next year, but I suspect there won’t be any other changes at the top for awhile.) I’ve read 19 of these. Incidentally, there is one book in the list that I hadn’t even heard of. Curiously, it’s #19.
