Linking Authors And Readers' Preferences

Talk about degrees of separation: Literature-Map - The Tourist Map of Literature is a site that allows you to type in the name of any author, and which will then give you the names of other authors that you may like to read in turn.

For example: typing in "Agatha Christie" brings up other names like Arthur Conan Doyle, Ellery Queen, Mary Higgins Clark, Patricia Cornwell, Sue Grafton, and Kathy Reichs. However, the site's not perfect in its listings. In addition to the above names, all of whom are mystery/suspense writers, the site also listed Enid Blyton and R.L. Stine, both children's authors and not writers whose books you'd put side-by-side with Death On The Nile or Murder On The Orient Express (granted though that the former has written children's mysteries while the latter writes children's horror/suspense).
