I've a book by Wykoff? Published in '86 which is about when I started college.
It's good & a lot still applies, but techniques get tweaked & tools improve..so while you can do well with an "older"book (being careful here)
Why not learn what's new?
It's not vastly different & you might not have the latest tools..but you gotta keep up to speed if It's your profession?
