Iron Range Research Center Photograph Collections
Holdings of the Iron Range Research Center
(IRRC) Archives include over 2,000 photographic collections containing
more than 150,000
In the past collections were
accessioned and organized by donor. The IRRCís in-house photographic lab
then copied collections on black & white or color transparency film
and made copy negatives of the original photographs. Contact sheets of the
negatives were produced, then each collection was assigned an accession
number, and each negative an individual negative number.
Collections are still accessioned and
organized by donor. Today however, photographs are electronically scanned.
Every collection receives an accession number and all photographs an
individual image number. Digital surrogates are created and assigned a
unique 8-digit ISO number, cataloged, and uploaded to a PastPerfect
photographic database for more efficient collection wide identification,
access and retrieval.
The in-house photographic digitization
lab is equipped to conduct custom digitization, reprinting and
presentation of black & white or color photographs.
