I have 32 of the books, if you want we can figure out a day for you to pick them up. That includes Good Omens though, so not everyone is Discworld. Apparently there are 41 Discworld novels published over 32 years.
I don’t see myself rereading them again and I’ve been pairing down my book collection a lot. Most are read 1-3 times only. Mix of hardcovers and soft.
Let me know via PM and I’ll give you my new address. I’m not at the old place where I hosted Dopefests.
If someone’s committed to reading the whole series, then I can fully support starting with The Colour of Magic.
If someone’s just going to read one book, and depending on how well they like it decide whether or not to continue, then I would not recommend starting there.
Not too long ago, Humble Bundle offered the whole set in ebook form for somewhere around $20. (But alas, that deal is no longer available.)
So, getting rid of them two at a time?
Ugh I can’t believe I set that up so perfectly. I will run away in shame on dozens of legs.
Exactly. 
Indeed, some of them are only classified as “comedy” just because they’re Discworld books. Monstrous Regiment, for instance, was no more comedic than any other dramatic novel, and it worked.
But yeah, silly humor has its place, too.
