No. 11 LibraryThing

LibraryThing was very straight forward. Amazon.com came up many times when it was searching for titles. I guess if a person has alot of time, they could "Chat" to other people who have similiar interests. Personally, I have my own system that works even if the electricity for the computer is off. My link is http://www.librarything.com/catalog/ktaetwins I put some basic stuff in, but this is not the end all or be all.
