The interface is very smooth, attractive, and intuitive, but at the moment, their database currently only holds science fiction books and fantasy books. They emphasize that while their service isn’t very functional yet, they are working on it.
You do have to register to use BookLamp, but it’s not a lengthy process. By registering, you can compare books, post in the forums, and suggest books to be added. But because of their limited collection, signing up for BookLamp now mostly just shows interest and support for the service.
BookLamp aspires to be a “Pandora for books”. BookLamp is also looking for suggestions for their future direction, so if you explore and have ideas, feel free to suggest some to them.
