On the BookLamp website, they explain their service as the following:
“What is Booklamp.org:
BookLamp.org matches readers to books through an analysis of writing styles, similar to the way that Pandora.com matches music lovers to new music. Do you like Stephen King’s It, but thought it was too long? BookLamp allows you to find books with a similar level of tone, tense, perspective, action, description, and dialog – while at the same time allowing you to specify details like… half the length. It’s impervious to outside influences – like advertising – that impact socially driven recommendation systems, and isn’t reliant on a large user base to work. Take a look at the above video to see how we do it in detail.”
Sounds like an interesting site to try. I would LOVE TO HEAR FROM YOU if you try it out.
