In general it is not a good idea to attach a barcode to a floppy disk, since it could cause the disk to get stuck in the disk drive. However, some unit libraries want the barcode attached directly to the disk. See the instructions for the individual unit libraries below. When in doubt, the barcode can always be attached to the permanent container for the disk. If a barcode is attached to a floppy disk, attach it in the label area. Write the call number on a peel-off self-adhesive label and attach it to the recessed label area of the disk (carefully, so as to not obscure essential publisher's information), or write the call number on the label with a felt-tip pen or soft pencil. Attach the call number label to the container.

Special labels: Apply to all CD-ROMs/DVD-ROMs that are not sound recordings
When cataloging computer disks as primary or accompanying material, affix a 'Warning of Copyright Restrictions' label somewhere on the bibliographic item. Examples of appropriate locations for this label are: on the computer disk container (either completely adhered or tipped in, being careful not to obscure text or graphics on the container itself), on a book pocket containing the disk, or on print material accompanying the disk. Use judgment in determining the best location for the label, but never apply the label to the computer disk itself.
