Hi Lauren,
The committees I've chaired have been called the Collections (or Collections Review) Committee. It's specific to the department, but leaves room to not just be about acquisitions or deaccessions. These committees have reviewed and accepted/declined new donation offers and deaccessioning recommendations, and have discussed other issues relating to collections like conservation needs, storage rearrangements, and possible inclusion of artifacts in public programming, as well as being part of the board-approved process of reviewing and updating our Collections Management Policy. For the latter, collections staff have taken the lead on any needed changes, presented them to the collections committee for consideration and approval, and then if approved, those changes go before the full board for final approval.
As to make-up of these committees, collections staff are included, of course, but at my previous museum the remainder of the committee was also the executive director, curator of exhibits, and one long-term museum volunteer from the community who had worked specifically in collections. That was a national museum and there were no board members on the committee, largely due to their proximity to the museum. At the museum I'm with now, the committee also includes the executive director and three members of the board since it is a county history museum and board members are local. At both places, interns are invited to sit in on the meetings and can participate and share thoughts, but don't officially vote.
There is real benefit, in my experience, to having multiple perspectives. These meetings always present opportunities to teach those that are not collections professionals and it can actually be a refreshing addition to hear other voices and ideas.
Hopefully this is helpful!
Best,
Angela Stanford
