Thank you, Will.

Subject: Re: [ARSCLIB] 78s from China

I'd strongly advise NOT applying alcohol to shellac discs. In experiments I've found that even when diluted it will have a seriously negative effect on the surface of the disc. It's often not apparent at the time, but revisiting the discs several months later the deterioration can be significant. I'd second George's suggestion that purified water, and if possible with a little wetting agent (surfactant), be used.

Regards
Will

Yes, you should change the sleeves; copy the text information for later retrieval (scan into a file.) There are archival sleeve available online.

Some of the USB turntables are set to capture the sound digitally, and CDs could be burned for use by professors from the digital files produced.

Storage: wood boxes of 13"x13" can be made. they will carry about 25 discs. Boxes can be stacked an moved when needed. The weight will be about that of a cement block.

Cleaning recordings: for a few 78s, I've used just some plain water, and really bad moldy records, I've used 99% isopropyl alcohol. Some in ARSC say this damages the disc eventually (changes chemicals) but if you have the scanned back up it may not matter too much. More serious is breakage.
