  1. Preserving Access to Multimedia Collections Al Cornish, cornish@wsu.edu Systems Librarian Washington State University Libraries

  2. Preservation example – Early Washington Maps Collection

  3. Preservation example – Early Washington Maps Collection • Bit preservation of Master TIFF files: • Online storage (RAID array, with scheduled backups) • Optical media storage (CD-R, DVD-R) • Considering outsourcing options

  4. Preservation support – Networking The three contributing Early Washington Maps collection libraries (University of Washington, Washington State University, Tacoma Public Library) are actively working with the National Geospatial Digital Archive (NGDA, URL http://www.ngda.org/) to support collection preservation.

  5. Preservation support – Networking • The National Geospatial Digital Archive (NGDA) is one of eight projects funded through the National Digital Information Infrastructure and Preservation Program (NDIIPP, URL http://www.digitalpreservation.gov/). • The NGDA host institutions are Stanford University and the University of California-Santa Barbara.

  6. Preservation support – Networking • Early Washington Maps content will be contributed to the NGDA repository. • Some issues to be resolved: • NGDA will develop technical specifications for content. • Agreements between host and contributing institutions.

  7. Preservation support - Software • Example: OCLC/DiMeMa CONTENTdm’s Full Resolution capability • Assists with the storage and archiving of full resolution files. • Formats supported include TIFF and MrSID; JPEG2000 support also available in CONTENTdm.

  8. The Preservation Task “Preservation is a collection management, or digital life cycle management, activity with a technology component but also associated policies and procedures.” Mackenzie Smith, “Exploring Variety in Digital Collections…”, Library Trends, Summer 2005

  9. Preservation example – WSU Oral History Project • Public web site using CONTENTdm (URL http://www.wsulibs.wsu.edu/oralhistoryproject/) • Content includes described, streamed audio files in RealAudio format; use of SMIL technology to create synchronized audio/transcript display • WAV format files serve as the preservation master
