One of our articles for a library class I’m taking mentions LibraryThing and having heard of it before, off I went to make a visit. Well I lost a lot of my weekend finding it pretty addictive and wanting to upload more and more of my library and using “power edit” to add metadata to multiple books at a time, looking at other peoples libraries of people who had books I had, reading their reviews, writing reviews, it was a blast. It was like a little book party.

Last Friday someone asked if I knew of a book about drawing, well I thought yes I have a lot of them and yet none of the names or titles were popping out at me, if I had been able to log on to LibraryThing, voila. Now I can do this and hopefully put links on blogs pointing to my library within LibraryThing.

Whenever you are not near your entire library you can access it, in some way. If you lose books for whatever reason, you still have a record.

Reference others suggestions about similiar books, communicate with others.

You get to add private or public comments like I really like this chapter or this thing about this book or its index is terrible, there is a favorite recipe on p.129; so years later it is all right there for you.

Wiki has some great info on LibraryThing and how fast it has grown, its working with OCLC, cooperative metadata generation, etc.

Some libraries have widgets on their sites linking you to LibraryThing.

It has many social networking features.
It is free, however after putting in ~150 books I decided to pay the little bit for a lifetime membership in order to be allowed to have over 200 books catalogued.
