I recently was introduced to a site called LibraryThing. It is a social networking site for book lovers. You can go to http://www.librarything.com/ and sign up for a free account. It will allow you to catalog books you have in your home library, find other people with similar reading interests, receive suggestions of books you may enjoy reading, talk about books on discussion forums, and submit and read book reviews. The cataloging info is based on Amazon, the Library of Congress and more than 680 other world libraries. I have just began cataloging books I have at home and look forward to adding titles on a regular basis. You use tagging to provide a subject access to your library of books, as well as searching other people's libraries.
The great thing about it is that it connects people based on the books they share. As you add a book to your library it connects you to other people on LibraryThing that have the same book in their library. This gives you access to other peoples libraries and and they have access to yours.
Another feature in the WikiThing option is I See Dead People's Books, which is a collection of libraries of famous dead people. This includes real as well as fictional. Another interesting feature is the Your Unsuggester. This is a list of books, based on what you already have in your library, that you are the least likely to want to add. This is a great opportunity to broaden your reading interests and read something really new and different.
It's a fun site where you can catalog your own Library online, and network with other people who share your reading interests. You can blog and talk in a variety of ways. Under Groups you can join others who have your own reading interests. I joined Librarians who LibraryThing. Other groups include Historical Fiction, Science Fiction Fans and many many more. It even has one for Name That Book for us who have read a book and cannot remember the name of it.
So if you love reading, then LibraryThing is the place for you. If you are looking for something new to read then LibraryThing is the place for you. If you are looking for people who share your reading interests then LibraryThing is the place for you. If you want to catalog your personal library at home then LibraryThing is the place for you.
