More like, books like The Anarchist’s Cookbook get stolen so often there’s really no point in buying them. Academic libraries are more likely to collect that kind of material.
ETA - the thing is, patrons hate that we can’t tell them what they checked out a year ago! There have also been incidents like a guy who disappeared hiking near IIRC Clemson and investigators thought maybe they could narrow down a search based on books he had checked out, but there was no record. Hey, tell somebody where you’re going, asshole!
