I just found this link and downloaded them myself. Some of the information may be of use for
NwN/NwN 2. Here are the titles -
Mathematics for Game Programming and Computer Graphics
Game Development with Blender and Godot
Functional Programming in Go
Fundamentals for Self-Taught Programmers
You will, of course, need an account at fanatical (or log-in using a Google account) to get these. Here is the link -
International Day of the Programmer 2023 Free Giveaway
Offer ends in just hours over 7 days from now (posted this on 15th September 2023).
Hope others find this useful.
[edit]
Found out by screwing up initially . There is a choice of three buttons to download each book - epub, pdf and all. Beware All is not what you may think. Pressing that button will download the sample code from the book you are trying to download, without the book. You need to also select either epub or pdf in order to get the book you were after. Also be aware that there are buttons to download pdf in each books description. These only download a six page sample of the book in question.
