I really enjoyed using Librarything. It is a good way to find books as well as connect with others reading the same type of books as you. I loved that just by searching you could find the exact copy of the book you have. Also going by author can help you find others by that author if you were unsure of other books he/she has written.
My link to my own librarything page is- http://www.librarything.com/catalog/KatrinaR
It was also interesting to see how popular the different books were that I choose to put on there. At least I know I am not the only one reading these books out there.
May get on line in holidays to do some discussing of books.
