New member, first post, although you’ll find I mostly lurk.
The two books by Knowbility partners aren’t exactly university focused textbooks, but are very good for training in accessibility.

So far 'Effective website development' (Darlington) and 'Principles of
web site design' (Skalr) have been proposed as possible options.
