Yep pretty much,
If you want arc welding, both lincoln and Miller haver great technical books.
If you want OA get a copy of "the oxyscetylene handbook" by Linde (now esab).

Unfortunately as we all know, its not always the right information thats spread, its whats sold the most. And unfortunately this series of books is everywhere! About the only place you dont see them is in school...or an engineers desk...hmmmm.
