-hp- had some very good app notes on spectrum analysis and impedance
mesurement. General Radio also published ap notes on various techniques
such as sound measurement. These publications were often ahead of any
text book.
They've never been restricted to being about how to use instruments.
Many are about how to perform measurements, and other
non-instrument-specific stuff. For example, the "bible" of that
mysterious "guard" terminal on high-end voltmeters: AN123, "Floating
Measurements and Guarding", from HP.
App notes also come from component manufacturers...usually (but not
always!) they are about applications for a specific component, but many
many of them are much more general. There's practically an EE degree's
worth of information distilled in the ones published by Linear
Technology over the years, for example.

Uhh...this is a very current term.

You completely missed the point of my comment.
