This is the link to my librarything account.
I reckon librarything is a great idea and would be ideal for book groups and that type of thing.
It's especially interesting to get reviews on books from other people to see their interpretation of such titles and to compare them to your own feelings on these books.
Librarything is also a great way to see what other people are reading & what is popular and what is not so popular.
All in all, a very useful tool.
