Which Doom editing book is better?

"Tricks of the Doom Programming Gurus" or "3D Game Alchemy"? I ask this because I've heard that the Alchemy book is just a reissue of the Guru book but there's over 100 pages missing. Also, are there any differences between the CDs that come with the books as well?

Seriously though, there's too much online information on Doom editing and too many new vanilla hacks and source port features for those guides to be much use - unless you want them for a collection.

I'm betting they're both old and incredibly outdated. Don't bother with either.

I basically just want them for a collection and the CDs they come with.

According to this thread...

...c.imp could probably send you the data on both those disks.

For hard copies, I guess ebay?

But again, the actual contents of the books would be useless. Unless you really want some documentation on using DEU.

I know where to find them. I just wanna know if there's any major differences between the two. Is the Alchemy book a reissue of the Guru book? Or are they completely different books?

Both books are authored by Steve Bemmer so a certain ammount of copy/paste is to be expected in 3D Game Alchemy. An extra 110 pages has been added to the main chapter "Creating Your Own Doom" - much of which probably relates to Hexen. The newer books smaller size is the result of trimming 210 pages from the chapter that explains how to use the editing tools.

All those pages did was basically copy text from the help files that came with the applications anyway. So they weren't very useful.

Anyway, I can't really answer the original question, as I only have Tricks of the Doom Programming Gurus.
