Catalog your books with Goodreads
I've previously written about Librarything, a book cataloging service, and now here I am again with another similar service, Goodreads. This service is very similar, but there are a few features which I like more here, making this a better solution for me.
The basics are the same. Find your books, add them, share them, indicate if you want to read a book and so on. However you can add your books using inline editing. With Library things you add a book, a page is loaded, you edit, then have to go back. With Goodreads there is a sort of inline popup box allowing you to add books much quicker. I own about 40 Terry Pratchett books, so this made my initial set up much easier.
There is also a cool book comparability test which shows you, based upon your reading of a lot of books, which books would be best for you. This, and other friendly features make this more appealing to me, while basically there is not much difference between the two. If you've already set one up extensively perhaps you're better off there, but if you are just starting I suggest going with Goodreads.
Community aspects have been approved in recent time. You can now make friends on Goodreads and see what they have been reading lately which may be an interesting thing to know especially if your friends have a similar taste as far as books are concerned.
You can now also search and browse books directly on the Goodreads website which provides you with a short description of the book, the overall rating of it on the site, and purchase options to get the most out of the site. You can also read user reviews which may be another interesting option to get third party opinions about a book you are interested in.
