• Facilities for Libraries to Share and Reuse
  Authority Data through the VIAF
• Linking Possibilities through Persistent
  Identifiers
• End User Search Facilities
• Multilingual and Multiscript Access
• Customizing Search and Display Facilities

Building the VIAF The VIAF Project, 2003 - 2007

• Project partners
• Library of Congress,German National Library,
  OCLC Online Computer Library Center
• Cooperative Agreement August 2003

11
The Goals

• Proof of the feasability of the VIAF concept
• Link PND and LCNAF records through a Virtual
  International Authority File
• Build a VIAF Prototype
