‡biblios.net is a free browser-based cataloging service with a data store containing over thirty million records.

‡biblios.net (pronounced 'biblios dot net') features a metadata editor 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 Public Domain Dedication and License.

[1] ‡biblios.net also includes a built-in federated search system, allowing catalogers to find records from any Z39.50 target.

Built-in forums and private messaging make finding help and communicating with others possible within the software.
