If you are looking for a web-based library management system, have a look at Web Librarian.
The Home Librarian maintains a database of your books, video tapes/DVDs/BluRays, records/cassettes/CDs, magazines, and other materials. This database can be searched by title, author, subject, or keyword. The database contains all of the ‘meta data’ about each item: title, author, subject, format, location, year published, publisher, description, category, etc. All of this information is available at your fingertips, right on your computer.
Now available: Beta Release 1 of Version 3.0 of the Home Librarian! This version uses a SQL Database back end and features access to Amazon.com’s huge database of information about books, CDs, and videos. Download it today and give it a try!
