We are in the process of using it as a "New Books" list. LT also has a lovely widget that we are going to include on our new web page. The widget displays the book covers of the new books (pulled from Amazon, I believe). You can click on a book cover and read more about it.

You can also create RSS feeds for new titles on any tag, such as nursing or cosmetology (yes, I am at a community college library), so that instructors or anyone can see new titles related to his/her interest will show up in a feed reader.

There are lots of possibilities. We do not use it in lieu of an online catalog, but it certainly makes a much more pleasing New Books list than simple text of titles and call numbers.

We are using it for a campus-wide book discussion. It gives our online students an opportunity to participate. So far, participation has been modest (around 30 posts), but I'm impressed that nearly all of that has been from our undergraduate students, who are not required to participate.

I use LibraryThing both personally and professionally. I use it to catalog the books I read, along with the books I own. This helps me with readers' advisory especially when I tag books properly. I used to work at a high school library and used to help create bibliographies and displays. I think it is wonderful tool and find the fees for use inexpensive and well worth it.

I wish the library where worked used LibraryThing for Libraries, but it doesn't.

I prefer shelfari since it lets you organize books as read, reading and plan to read. It really helps me keep track of the books I want to read.

I have put a lot of my own books into LibraryThing and for the moment they are just sitting there. Though I consider it a good inventory should I need it one day. I wish they did CDs and DVDs as well.

I also introduced it to a small library in Nicaragua as a simple way to catalog their books. They have a version for non-profit organizations that allows for more records at a reasonable price and last I knew were developing their LibraryThing for Libraries. As I mentioned though, I have not poked around in a while to see how the additions and improvements are coming along.

I use LibraryThing for my personal collection and my Church Library. It is very easy to add books to your collection, it basicly takes information from the Library of Congress or Amazon, or whatever library you pick from its list. Then its very simple to add information about the specific copy that you have, down to copyright, number of pages, and a scanned image of the cover!

Once added to your collection, it is simple to add tags, which allow you to add subject terms not already attached, note where you physically have the book, or even give the book an individual number. There are also features on LibraryThing that allow you to keep track of if you have read the book, rate the book, write a book review, or add to a "collection" of books on a wishlist of books you want to get. You can even interact with other members who have a certain book, and view their collection. You can even get a list of recomended books and other members based on what is in your collection.

This is just a breif overview, LibraryThing is full of neat gadgets that help you find books to read, places holding book events, and other readers like you. Enjoy and be aware, its addicting.

I have attempted, and mostly failed due to various time/moving factors, to catalog my personal collection on Library Thing. The social networking aspects, particularly "meeting" others with similar books to my more-unusual ones is the main attractor to me. I helped a gardening club set up a catalog of its books with it, which is, as others have said, very easy, and meant all members could see the available reference material online.

My library also uses Library Thing for Libraries, and the various associated widgets. Given that topic searches work fairly badly on our OPAC, the tag clouds have become a popular way for both customers and staff to search for "steampunk" or even "chick lit". The comments and reviews are less popular and well used, based on our experience so far.

I use Library Thing for my collection at home! It is fast and easy -- even my husband can enter books into it! I love the book covers, that way I remember visually where the book is on my shelves (different rooms).

For the most part, I use LibraryThing (LT) for my personal use. Occasionally I will use it for book ideas when I am making a reading list. I can usually find what I need by searching our library's catalog, but sometimes a LT tag search will give me some books that did not show up in my catalog search. Certainly further research is needed to make sure the tag and the book is accurate, but it is a good starting point. I also enjoy reading people's reviews and use them to help choose my personal reading choices.

I use LT personally to catalog books I own. This is very helpful when at the bookstore -- I can go to LibraryThing on my phone and search my personal catalog. Because that's the primary reason I use it, and it's more difficult to determine what category and tags are on a book when searching for it on a cell phone, I catalog those titles I've actually read on a different service. I got a cuecat for ease of scanning (http://www.librarything.com/cuecat) which could work better, but is cute and helpful when adding a pile of new books.

Professionally, our teen department uses a LT account to keep track of new books. Since our catalog doesn't allow users to search within the teen collection, we can use LT to search for titles about specific titles, and tag-mash comes in handy when developing booklists.

I use LibraryThing to catalog my books at home. Since it's online, the ability to jog my memory and see if I own a particular title is a useful. I also love the utter geekiness of being able to assign my own call numbers. OK, it's a cataloger thing. I understand that you might not understand. But it's still fun.

LibraryThing is one of the best things since Dr. Carver invented peanut butter.
