James: Thank you for the update as to what the current thinking is at L.C. It has been almost a decade since I was doing my graduate work in D.C. and miss having the opportunity to discuss preservation issues with Gerald Gibson. I hope that he is doing well.

The Library currently still uses reel to reel tape for preservation work, though it also makes simultaneous copies on DAT for playback purposes. Of course the originals are kept and stored at the best conditions we can provide. However there are several individuals at the Library who are doing a great deal of work to set up a long-term digital repository. They are taking into account all of the issues that have been brought up in the excellent discussion on the list, especially the points raised by Chris Lacinak. I have been involved a little with this group, but my input has been more towards obtaining the highest quality analog signal for digitization, rather than what happens with the files. But clearly both sides are important. The reality is that analog presevation will soon not be possible, and everyone concerned at the Library realizes this. The issue is to make the transition to digital in the best possible way. This requires not only research but a careful assessment of the available scientific studies. As far as I know, this is what is being done here. James >>> [log in to unmask] 06/25/03 04:41PM >>> The question actually posted specifically asked about long term preservation. The problem is not whether or not CD's and DVD's will last for posterity, but if the players will still be around in the future. Although digital and optical media is wonderful for providing access, I believe that the Library of Congress still promotes utilizing reel-to-reels to serve as their preservation copies. Can someone please correct me, if I am wrong.

CD-R and DVD are also desirable because the drive head is not in contact with the media during operation. J. Hartke Media Sciences, Inc.
