1. Forgery, forgery, everywhere
2. Tools, equipment, and other resources
3. Methods of forgery: Alteration
4. Methods of forgery: Casting
5. Methods of forgery: Creating dies, part 1
6. Methods of forgery: Creating dies, part 2
7. Collars and edge markings
8. Planchets
9. Minting machinery and processes
10. Wear, aging, and patina (which discusses, among other things, the use of urine to produce a patina!)
11. Detection and protection

Sounds interesting to guard oneself against fraudulent sellers. Being from 2004, do you think it is still up to date with the current forgeries that are seen on the markets ?

Being new to the subject, I really don't have much idea. For all I know, forgers are probably 3D-printing them now.  :P

On a related note, the series of articles here is also quite useful.

I had done an ebook on fake coins of India giving out the various techniques employed by forgers.

Yes there days for India and British India we see quite a few well done forgeries, these look to be 3-D printed. With this technique, it is very difficult to call out the coin, more so if they use the right metal combination. There are still tell tale signs in terms of finish and lettering specially the smaller ones.
