At university, students would often leave library books they were studying on the tables to be picked up and shelved by library staff. I would sometimes read the pages they left open.

Once I came upon a table full of social work books aimed at undergraduates. It was the most abject anti-drug (mostly marijuana) propaganda, almost approaching Reefer Madness levels. They make sure the people who wind up getting jobs as case managers have had their fill of the Kool-Aid.
