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.
