My friend teaches typography at an fine arts and design school and "Elements" is the textbook. When I went to art school in the 90s it was also one of my textbooks (though it was still a relatively new book at the time). It's one of the few books that's remained on my shelf for the 20ish years since I bought it. I still reference it regularly.

I find it a nice-looking book too, which is unsurprisingly expected for its nature.
