Book on textual transmission of ancient manuscripts

Some time ago someone here posted the title of a book that describes the difficulty of reconstructing the original text of classical texts from copies that date many centuries later. Could you refresh my memory what the title and author was of that book? I want to see if I can get my hands on a copy or borrow one through our university library. Thanks!

This perhaps?

Scribes and scholars : a guide to the transmission of Greek and Latin literature / by L.D. Reynolds and N.G. Wilson.-- 3rd ed.-- Oxford, Oxford University Press 1991.

On this topic, the splendid Antigone site recently published Jim Willis’s witty 1991 lecture The Science Of Blunders: Confessions Of A Textual Critic The Science of Blunders: Confessions of a Textual Critic – Antigone

That’s the title I was looking for, thanks!
