Passage 1 of the Colour of Magic: 'bazaars' was misspelled 'bazarrs'.
There were a couple of other things that didn't match the paperback copy
I recently recovered from loan: 'radiation' should be 'radiations', and
'dark' was omitted from 'a tall dark figure'.
Unlike the later Harper editions, the early Signet ones retain British
spelling (at least for 'colour'). I failed to find the second passsage
via flipping through the pages, so wasn't able to proof-check that one.
