What's it Do?
OPAC imports and searches library catalog records in Drupal. Anyone who works with library catalogs knows that's easier said than done. This is a big, ambitious project and needs more reviewers, especially people working with Drupal and libraries.
Many libraries have moved to Drupal already, for everything except their library catalogs. Library catalogs are too often stuck in a noticeably different interface, a completely separate system that doesn't integrate well with the main Drupal website for the library. OPAC doesn't entirely solve this problem, but it's a start, getting important catalog data into Drupal where it can be directly integrated with the rest of a library's Drupal site.
