I'm looking for a few websites or lists of great novels or books
(however many you can find for $5 - your determination).  I'm more
interested in fiction from the 1700's onward but any all inclusive
lists you find are fine.  I want to get some new ideas for books I may
have missed that I probably should read eventually.

Hello.
