‡biblios.net is a free browser-based cataloging service with a data store containing over thirty-million records. It features an intuitive metadata editor complete with templates, macros, authority auto-completion and embedded, context-sensitive help.

Catalogers can use and contribute to the database without restrictions because records in ‡biblios.net are freely-licensed under the Open Data Commons, making the service the world's largest repository of freely-licensed library records. The data is maintained by ‡biblios.net users similar to the way model used by Wikipedia.

‡biblios.net also includes a built-in federated search system allowing catalogers to find records from any Z39.50 target. A central Search Target Registry, seeded with over 2,000 Z39.50 servers, makes it easy for catalogers to find, create and share Z39.50 targets.

In addition to offering a cutting-edge cataloging interface, ‡biblios.net offers a unique social cataloging environment. Built-in forums and private messaging make finding help and communicating with other users a cinch.
