GOG can give with the game the books of doom?
I can´t find them anywhere.

They're not very good. The writer changed them from demons to genetic modifications by alien invaders. The first two novels at least ATTEMPT to be adaptations of the first two games, but the third and fourth novels have nothing to do with the franchise.

If you want them, all the novels are available as ebooks in Amazon:

Original Doom:
- Book 1: Knee-Deep in the Dead https://www.amazon.com/gp/product/B00AK804G2
- Book 2: Hell on Earth https://www.amazon.com/gp/product/B00AKA5LVS
- Book 3: Infernal Sky https://www.amazon.com/gp/product/B00AKA5LY0

And even the movie novelization: https://www.amazon.com/Doom-John-Shirley-ebook/dp/B000FCKI3C/

I had no idea there was a movie novelization...
