Many years ago--you will know how many when I mention typewriter and carbon paper--I was looking at television, and saw an interview with Rex Stout. Stout said he enjoyed writing but hated to rewrite, so he wrote slowly and carefully, and never revised. ""That is for me!"" I said. I bought lots of ""carbon sets,"" single-use carbon paper packed with sheets of thin paper attached, and wrote all my good novels of the 1970s slowly, being careful not to make mistakes, with four carbons--and except for ignorant misspellings and misplaced punctuation, and a very few typos, what I typed is what is in the printed book. Today, I write more or less the same way--but the advent of the word processor allows one to think on the screen, try things out and see how they look, and this gives rise to other kinds of errors, (see the comments following chapters of the serialized Adventures of a Cat-Whiskered Girl, on this website). I will not speak of errors and corrections made by the publisher and printer after the manuscript has left my hands. No book is perfect, especially mine, and this does not cause me any concern. If you are concerned, you can buy the paperback, and even search for copies of the bound uncorrected proofs that publishers send out to reviewers, and compare them to the raw text we post as serial chapters here before publication. Then you will know all. I have no idea why you would want to, but God bless you. I do not know the work of R.A. Lafferty.
