Trying to find Book 1/2 and Book D?

[137beth]

Those books are all going to be hard to find in print. You are basically looking for a used seller at this point.

Book 1 and 2 can be bought in digital form at Gumroad (and IIRC, have a bit of extra commentary beyond the print version, as the digital versions were published years later):
Book 1: https://richburlew.gumroad.com/l/ootsdcf
Book 2: https://richburlew.gumroad.com/l/ootsncfpb

Snip Snails and Dragon Tails has never had a digital version, and the print version is long out of print. Hopefully Rich will do a digital version at some point, but that's not the case now. So yeah, you'd just have to look for someone selling a used copy.

I think the title of the OP was referring to Book 1/2, i.e. Good Deeds Gone Unpunished, not books 1 or 2. Peelee already linked to where you can find the PDF of that.

I'm in the camp that is hoping to eventually get a PDF of SSaDT. Maybe some day.
