Mass Market paperbacks. These small, relatively harmless books sow much discord among the branch and Central library staff in my system. There are some who love them, most don't think anything about them one way or the other, and some loathe them. They are synonymous with "genre" literature with is synonymous with "bad" or "trash" or "junk" books. But you've all dealt with that attitude before so no need to re-hash that here. I don't have a separate budget for mass market paperbacks, so I normally come across them during my everyday ordering or when I'm ordering replacements. Replacements: when ordering replacements, I first have to consider my options. Often, only a mass market paperback edition is available, so that's what I get. If there are mass market and trade paperback editions available, then it becomes a choice of what we have in the system or what we've had previously, how big is the book, and price.
