Canyon del Oro High School

Pretty cool you put in an author’s name and it shows a map of other authors. The closer the authors are on the map, the more alike they are.

This has sliding bars to choose what you want. Some of the choices are HAPPY -SAD, SHORT-LONG.

I have always liked this site because it used TAG clouds to show what the book is about.

Library Thing's book suggester and UNsuggester which is interesting.
