I have heard it said that one flaw in Flint's work - in this case as related to Flint's editorship of the republished works of James Schmitz - is that Flint is (or was) a little too quick to apply the editorial pen.

Otherwise, I'm glad he's taken up the cause of republishing (and therefore preserving) science fiction older than some of my friends and acquaintances (to say nothing of their children).
