Do we need to keep all of our collections forever?
No! Sometimes institutional and collection practices change, and collections must change with them. In these cases, collections should be reappraised and possibly deaccessioned. This guide from the Society of American Archivists outlines how to do that, and helps with deciding what to keep and what to remove.
How do I prevent our museum from accepting more items that don’t fit our mission?
A strong and specific collecting policy for your institution will allow you to decline items that don’t fit your collection. This is a great opportunity to create, revise, or check in with your Collections Policy.
