You can find entertaining stuff there. My interests can be really niche. I remember once finding an amazing book in our college library from the sixties or seventies about the use of LSD in treating psychiatric disorders. While I didn't agree with all the suggestions in there, it was a fascinating time capsule (with colour illustrations, many of them by patients). With the microdosing debate, it's probably relevant again.

Yet when I took the book off the shelf it looked like no one had touched it in many years.
