Practice has shown that the number of CDs in the several hundreds, store them in a standard plastic box is very uncomfortable, and they occupy a decent place.
Simple solution - storing discs in paper bags, which are clearly legible and contain all the necessary information - category (video, music, software and so on. N.), Disc number (for quick searching through programs catalogers), name and description files .
The file contains a scan of the CDLabel.cdr envelope.
Do not be amiss and "post-reminder" for forgetful friends, not hurrying back drive rightful owner!
