I wonder how having the PostScript drafts of John Ousterhout's reference
book ``Tcl and the Tk Toolkit'' freely available has affected sales for
Addison-Wesley? My guess (and it is just a guess) is that it either
hasn't effected them at all, or has even improved sales. Why? Because I
used the PostScript draft extensively before the book was published and I
still do. But I got the book as soon as I could because it was nice to
have the full index there (which wasn't in the draft) and to be able to
read it where I currently can't easily read an electronic version (on my
Mac for example :-) ). Brent Welch is doing likewise with his new book.

So maybe all this talk of copy protection and encryption, etc is a bit of
smoke screen if free distributing the information in one format helps the
sales of the same (or similar) information in another format.
