Query: I can't believe this is still in print. Or ever was in print!

I found this page because I was feeling nostalgic and chatting with a friend about the worst textbook I ever used.We used this book for intermediate E&M; in the late 90s (taught by Martin Olssen, the second author). The only consistent things about it were the fundamental errors in the physics that graced virtually every single chapter: from algebraic blunders to reversed senses of motion to wrong integrals, this book reads like a poorly transcribed "first draft" of the course's lecture notes. Literally everyone who did well that term bought (and studied from) Griffiths, to which I direct any reader who'd consider this ghastly mistake.
