Fun website for bibliophiles

My hometown library is sponsoring a summer reading contest for adults that involves a tic-tac-toe inspired game. I won't go into the details now, but, one of the reading categories is called, "Memories," and is reserved for books that were best sellers through the course of the 20th Century.

The site is:

It's fun to read the lists of best sellers which are ordered by decades. So far, I have only looked into the first two decades of the century and find many names mysterious!

Besides, the lists would make great teaching tools.
