Material restricted to honor the wish of a donor is an example of a very important restriction. The Reading Room staff must be able to identify such things, and keep from inadvertently bringing them to readers. Such items might have a label that says restricted, consult curatorial staff. Or there maybe a note in the finding aid that specifies the nature, extent, and time period for such restrictions, and when they would be lifted. This detailed information does not need to appear on any labels. The labels are not considered as "authoritative" as the specifications laid out in the finding aid, though labeling them restricted is again, very important to adhere to.
A single item that has a restriction lifted will 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".
