Spectrum Union Catalog is the complete catalog internet public access IPAC and inter-library ILL solution for multiple-library districts and multiple-branch public libraries. Every library in the Union whether they are automated with Spectrum Athena or any other library software containing true MARC record will enjoy access to the complete holdings of the district through a central unified database – making resource and MARC record sharing easy and convenient. Union Catalog is an effective district-wide solution, because every member library can effectively search the Union database with a browser Explorer or Netscape regardless of the automation program they use and regardless of whether they’re using a Windows or Macintosh computer.
