I cataloged my personal library with Library Thing (http://www.librarything.com) and this is just great.
Now I don't have to memorize all the books that I have, and I can share my literary flavors with everyone.

I added to my blog a random selection of 3 books from my library - you an see them on the right just below my Profile. Every time you visit, you will see 3 new books.
you are most welcome to take a look at these books and comment.
