Is there an IMDB.com-type welsite for the book world?

You can try the Internet Book List, although currently the content on there isn’t great.

I often use sites like Wikipedia and Amazon for info about books.

Wikipedia is particularly good. But there isn’t a particularly good dedicated resource that I’m aware of.

I have not found a good single resource either. For current books, I use Amazon a lot. I get some details like plot synopses, sometimes a peek at pages, author and publisher info, etc. For mysteries, this one is a favorite site of mine: www.mysteriousbookshop.com. IF you know the author, nowadays many have their own web sites. I use those a lot.

I don’t know of one website. My first thought was the Library of Congress which seems difficult to use. There is a website called Allbooks.com which classifies books by character, plot, setting, and writing style. The NY Times Book Review would be a good source. You must register to use this site. Hope this helps.

Goodreads is a great website for finding books and their various editions, as well as reader ratings and reviews. There are author pages, too, with bios and other info. There is a forum for quotes, book swaps, and even pre-publish giveaway offers. There is also a member-submitted trivia feature, but it’s not just a list, like in IMDB – it’s made up of multiple-choice questions, and you have to at least guess to see the right answer. The tivia is usually just character & plot stuff you would know if you had read the book.

This probably isn’t exactly what you’re looking for, but since what you’re looking for might not exist, it’s probably worth checking out.

…and if YOU end up creating an IBDB-type webiste, let me know!
