I'm using Goodreads too to track my reading habits. I'm writing a short review for each book I've read so maybe in a few years time I can take a look back and see if I still agree with how I felt about the book.
This is the number one reason why I started blogging about the books I have read. I know that my reviews are not great as compared to other bloggers, but really, they suit me just fine.
I use to GoodReads for keeping track of books read, and books that i want to read. Then I fell behind in keeping track; updating. Now, i am not certain what I should do. Update my account (grr...time needed to do this), ignore what i have not updated and move on, start a new account, stop using GR completely?? Those are my personal burning questions that I have been unable to answer.
In the meantime, I am use Google spreadsheet to keep track of books that I want to read; the books I come across this year as I just started this list.
I do use Collectorz to catalog books (and, once the comic database is done for Macs, I'll get that one too). I'm a big, big fan. It has an online bit, but I've never really tried it... be curious if anyone else has! It is about £20, but there's a free trial... I did that and got suckered in for life.

I looked into Collectorz, thanks for the link. It looks neat. Do you find it hard to manage? Do you use a scanner to input your books? If so, how do you like it?
