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.
