PMB is a completely free ILS (Integrated Library management System). The domain of software for libraries is almost exclusively occupied by proprietary products. We are some librarians, users and developers deploring this state of affairs.
PMB is based on web technology. This is what we sometimes call a 'web-app'. PMB requires an HTTP server (such as Apache, but this is not an obligation), the MySQL database and the PHP language.
The main functions of PMB are :
Supporting the UNIMARC format
Authorities management (authors, publishers, series, subjects...)
Management of loans, holds, borrowers...
A user-friendly configuration
The ability to import full bibliographic records
A user-friendly OPAC integrating a browser
Loans management with a module designed to serve even the very small establishments
Serials management
Simple administration procedures that can be handled easily even by the library staff...
More details can be found at www.sigb.net where you will also find an online demo version, the PMB users Web page, and the latest versions of the Installation Guide, the User Guide, and the Administrator Guide.
