Just found this interesting link that I'm posting here on my quilting blog as well. The site produces a map of authors. For example: If you read a particular author and enjoy his/her work, you can get a map of what other people read who also read that author. Not only can it introduce you to new authors, but it can remind you of authors that have slipped your mind.
For example, people who read Amy Tan may also read Anna Quindlan, Gregory Maguire, Minette Walters, etc.
People who enjoy Barbara Kingsolver may also be reading Joyce Carol Oates, Jane Smiley, Margaret Atwood, Annie Proulx.
What you realize is that your own reading patterns are repeated by so many others. And it's fun to see the connections between authors
.Goethe: Heinrich Boll, Charlotte Bronte, Descartes, Nietzsche, Bertold Brecht.
I must leave this alone!!! But there are so many other authors that I've enjoyed that demand attention...
