Collection Development

I had student workers go through a couple of years of old ILL requests and enter the call numbers of the requested items on an Excel spreadsheet. Now I'm going through the high-demand subjects (which turn out to be religion, literature, and psychology) to see if there's anything we need. I was surprised to learn we don't have the Malleus Maleficarum, the classic witchhunter's manual from 15th-century Europe. I'll order it as soon as the new fiscal year rolls around.
