What clue on a book or play binding, front, or back matter says it’s been partially censored.

I remember reading a couple things for high school classes which I later learned had excerpts removed (and I guess rewriting is now occurring too) but like any high school student I didn’t thoroughly note the matter pages. Would there have been some statement beyond edition and year?

Funny story one English teacher brought in the full version of one instance, Macbeth I think, and read us the forbidden passages. It was marvellous.
