Preservation Film: Platform for Digital Access Systems.
Jones, C. Lee
Preservation efforts for an increasingly digitally oriented future have turned to advanced and improved methods of preservation on microfilm, which has a life expectancy of more than 500 years when properly prepared, stored, and managed, and can support a wide range of digital access systems. Computer controlled cameras can provide significantly higher resolution than cameras previously used for microfilming materials. High resolution microfilm can be easily scanned into digital formats, retains more resolution than current scanning technology can capture, and precludes a dependence upon a fast changing digital environment. Another critical factor for easier and higher quality scanning is narrow film density range. In addition, continuous tone filming (CTF) process successfully captures continuous tone images of photographs, negatives, prints, and heavily illustrated materials and adheres to preservation standards. Vendors of preservation filming services have focused recent service enhancements on reducing the cost of putting material on film. However, the preservation reformatting goal of every library, archive, museum and historical society needs to be to prepare preservation microfilm for the digital present and future. To simply reformat endangered materials into a form resistant to scanning or one that complicates scanning is a serious disservice to scholars and researchers of the future. (Author/SWC)
