It's a bit less of a thing than it used to be, but disposable books on technology were a thing for quite a while too. Think titles like "iPhone 6 for Dummies", "Learn Flash in 24 Hours", or "Windows 8 for Seniors" - there are a lot of books which were written (usually on the cheap) for a specific audience at a specific time, and which have no enduring value.

Also along these lines: test prep and study guide books. Same deal really.
