Re: [ARSCLIST] disaster recovery information for less common audio materials



There may still be on the net the disaster recovery plan I wrote for the Boston Public Library after its flood in 2000. I think I addressed some of these.

Edisons are lamenated, often with fine wood powder inside which absorb moiture easily. My recommendation, discard them.

Water should not affect the belts. Fire will.

Wire. It should be stainless steel (but is not always.) This is pretty robust in storage but may be subject to possible tangling if suddenly heated and cooled. Also, of course, the magnetic signal may be affected by intense heat. Not much you can do about the last issue.

One thing I recommend is a scanner and/or xerox machine to save the documentation. It requires someone adept at numbering to tie the artifact to the affiliated debris or its picture. During the recovery process, there's a whole lot of triage going on to avoid poising the rescuers.

Subject: [ARSCLIST] disaster recovery information for less common audio materials



hello all-

george blood suggested i poll this listserv for the answer(s) to this question:

i am currently creating a "cheat sheet" for wet disaster recovery of audio materials for a presentation at ALA. the categories are: media type, action time, handling precautions, prep/cleaning (more like rinsing) materials, and drying materials.

there is a good deal of information on recovery of magnetic tape, vinyl and acetate/shellac discs, but almost nothing on more obscure media such as the following:

wax media (cylinders, disc masters)
phenol discs (edison diamond discs)
vulcanite (berliner) discs
wire recordings
magnetic belt recordings (dictation)
grooved belt recordings (dictation)
any and all playback equipment

does anyone have any guidance as to what i can advise people on doing to recovery these materials if they get wet? i have some information, and some of it seems obvious in terms of materials science, but i would prefer to hear from people who have had direct experience with recovering these materials. you will (of course) be properly credited for your efforts.

i appreciate any and all insight you all can provide me!

thank you so much,
sincerely,
tara kennedy
