    <pre> We have labels on the CD cases for our photodigitization project because everyone told us not to label or mark on CDs. Each CD does have a unique serial number generated by the manufacturer. I keep a database of information that includes an ID #, the disk #, collection initials, photo numbers on the CD, shipment #, batch #, manufacturer's serial #, QC performed (checkbox), loaded (checkbox to indicate that the images have been loaded on our image server), and comments.

    This has worked well for us. When we want to retrieve a CD, we check the database and can tell immediately which ID# it is. CDs are stored in numerical order by ID #.

    Some folks say that using a water-based ink pen is OK, but in general writing on CDs should be avoided if at all possible. I believe all CDs (at least the good ones) have a unique number assigned by the manufacturer and located on their inner hub, which you can use to create a separate index to their contents.
