A single item that has a restriction lifted should look like this screenshot below. The 500 field in the bib record and the 506 field in the holdings record is changed to "Open for research". In this instance, the call number is 93M-194.
RESTRICTED LABELS (when necessary)
All pre-1600 manuscripts are restricted, regardless of call number. Because this is already well-known by the Reading Room, we don't label such items restricted, unless perhaps there is a special archival copy to make readers aware of, or some other special restriction called for by the curator.
All other manuscripts from the time periods after 1600 will be marked restricted according to the dictates of the HOLLIS holdings record. The wording on the label is short. Sometimes it merely says "RESTRICTED". Sometimes it is possible and appropriate to list the reason for the restriction as below:

AUIOVISUAL AND DIGITAL RESTRICTIONS
Audiovisual material and devices like cell phones are always restricted until data derived from them is cataloged and/or a surrogate is available. However we don't label audio and videocassetts as RESTRICTED because their status might change, and it is understood by staff who perform public services duties. Listening devices, such as cell phones, for digital material are in the same category.
