For people who love to read books and want to have a large collection of books, they would love the LibraryThing service. LibraryThing is an online service to help people catalog their books easily. They can access their catalog from anywhere including on their mobile phone. For those who are interested in LibraryThing, there is a free account that allows them to store up to two hundred books in their private database. Paid accounts will allow them to catalog any number of books they want.
LibraryThing is a full-powered cataloging application. It searches the Library of Congress, all five national Amazon sites, and more than sixty world library. This service also has a recommendations site and a discussion board. This is where people suggest whether the book is good or not. It is also where all the readers get together and give feedback about the books. This is an excellent way to get reviews on the books.
