Many of our spaces are closed down for the foreseeable future and those of us still involved in collections are maintaining and caretaking for our facilities. It is a good time to remind ourselves of the 10 Agents of Deterioration, and how they can inform our planning and prioritizing.  The last time I worked for an institution that had to shut down for a long time was after a natural disaster, and I was an intern. Safeguarding against these agents is the only way to responsibly manage our collections.
