Well, sure enough, I'm getting to the bottom of this heinous crime! I
just discovered that the culprit did, indeed, steal my book, but he had
the chutzpah to sneak an EXACT DUPLICATE into my briefcase! The nerve of
some people today!! He even went so far as to cover it with MY fingerprints!

The exact title of the article is: "Air-Cored Inductors for Audio",
initially printed in Proceedings of the I.R.E.E (Australia), vol. 36,
pp. 329-333 (Oct. 1975), later reprinted in the Journal of the Audio
Engineering Society, vol. 24, no. 5, pp. 374-378 (Jul. 1976),
with a followup in the Journal of the Audio Engineering Society, 
vol. 24, no. 10, pp. 830-832 (Dec. 1976).
