Need to catalogue your personal or home library?
LibraryThing, an online service, is excellent. It works by allowing users to catalogue their books in the LibraryThing database. To simplify the task and save keying, records can be retrieved simply from Amazon or from an increasing array of libraries, including the Library of Congress.
No software is needed. A free account allows for up to 200 books. A paid lifetime account allows for any number of books. As well as cataloging your own library, you can apply subject tags to books, look at other people’s libraries, etc. You can download a file of your data. The Beta version is improving rapidly and I like it a lot.
So far I’ve catalogued over 600 of my books. I’m about half done.
LibraryThing allows users to see what books they hold in common with other users.
