I currently volunteer at a county museum where we need keys to access the gallery talk materials. Most of these materials are stored in large upright locked cabinets on wheels and kept in the galleries. The keys are tied onto wooden blocks the size of a deck of cards and kept in a drawer at the front desk. There is one closet which keeps some of the larger taxidermy examples used in gallery talks, and since this closet contains building system elements, we have to sign out the closet key from the security staff. This system works especially if museum staff is not available to open the education department which supervises the volunteer force.
