Dye fading in color slides is inevitable, but longer retention can be had with low humidity/temperature storage. "Archival" processing for silver halide negatives can produce a useful image life well beyond 150 years. Over the past 20 years, I have lost more electronically stored data than I care to think about, even with regular back up procedures in place. If part of your imaging project goals is preservation, it only makes sense to provide as stable as possible analog AND digital copies, much as we who still microfilm make a master negative, duplicating negative, and a user copy, each stored at a different site. (I would love to provide a digital user copy of all my microfilm to the end users, but I would not eliminate the other 2 film copies.)Bob Henneberger INTERNET:mailto:bhennebe@uga.cc.uga.edu Computer Services WWW:scarlett.libs.uga.edu Preservation services Compu$erv:73727,2615 University of Georgia Libaries Athens, GA 30602
