Linda L Briggs, "Preserving History in Multimedia: An Interview with Stanford's Michael Keller," Campus Technology, 7/9/2008.
Keller, who is university librarian and director of academic information resources at Stanford, is interviewed in this short article about "a worldwide effort to digitally preserve vast amounts of material from history, both aging paper documents and very recent digital content." If you would like an overview, more like sound bites to complex questions, take a look.
He was asked if "part of it is a format problem. Is part of the problem that any media simply fades over time?" and gave a for instance explaining how with mag tape, if "you leave them alone and you don't rewind the tapes once a year or so, eventually, the magnetic carrier and the physical carrier separate. When that happens, you may not be able to play [the tape] at all, or, if you do run it through the readers, you may discover that it's the last time you can read them."
Back around 2001, when working on some of the 7" and 11" tapes from 1970s and 1980s contained in the Tucson Meet Yourself festival collection, we encountered this very problem. These tapes hadn't been spooled for decades, much less once or twice a year. Fortunately for us, we had Lee Furr on campus in the College of Fine Arts. Lee was a semi-retired audio engineer and, anecdotally, Buck Owens' sound guy. It was my understanding that Lee donated the equipment from his Tucson business to the UA and was working part-time in the Treistman Center. Lee contacted someone he knew who had worked for at 3M who explained how to deal with "sticky shed syndrome" the very condition Keller alludes to. Solely due to Lee's expertise and diligence, those TMY tapes were successfully spooled, digitized and are available to the public in the Music of the Southwest website. In Googling "sticky shed syndrome" I saw an article that reminded me that the tapes first needed to be "baked." I had to buy Lee a fruit hydrocollator. He put the tapes in the hydrocollator overnight to "bake" them and could then run them through a soft spooler. It was very interesting to observe all of this.
