Which library web app should I use?

Dear fellow Tumblrs,

I currently have a small collection of books listed in a LibraryThing account, and I pull LibraryThing’s RSS feed into my Tumblr account so new books show up whenever I add them.

However, LibraryThing inserts CSS code into my tumblelog. I don’t like this very much.

I see that Google has its own online library app that’s part of Google Book Search. Has anyone used it? Is it better? Are there even better things out there?

Feel free to reblog this or e-mail me. Thanks y’all.

Sincerely, Jesse
