Maybe, but I’ve searched for it many times out of curiosity, but have never managed to locate it online, and wouldn’t know if paper copies exist.

From Wikipedia, I get to https://web.archive.org/web/20010204033600/http://publib.bou...

That has one live link: https://web.archive.org/web/20010107084700/http://publib.bou..., but from there, the trail runs dead.

Do you have a link?

PDF link in the box on the right.

Thanks! No pictures and way uglier than Apple’s HIG book, but much more than I ever found.

pdf contains plenty of labels "PICTURE 73 HERE" but not pictures. That's pretty important for a book about UI...
