arsclist Relative humidity and storage

[ickis1@xxxxxxxx]

I'm new to the list and was wondering if there is an accepted standard
relative humidity and temperature guideline for storage of the following
types of media:

Brown wax cylinders
2 minute black wax cylinders
4 minute black wax ("Amberol") cylinders
Celluloid cylinders (Indestructibles and Blue Amberols)
Berliner discs
Standard shellac discs
Wire recordings
LP's
Instantaneous discs i.e. "acetates", "soft cuts", "lacquers", etc. (a rose
by any other name...)  both paper and metal base
Plastic dictation media (including 'Soundscriber' discs, 'Audograph' discs,
and 'Dictabelt' types)
Reel to reel audio tape

Are the guidelines similar for all formats in question, or do they differ
depending upon the type of material (wax as opposed to shellac, specific
formulation, etc.)?

Thanks!
