In between the topic drifts I seem to recall someone said something about redesigning the schematic circuit diagrams in A of E to conform to some kind of standards.
Please don't. A of E is almost the only academically published book I've ever seen with consistently good schematics.
Schematics are a living language. Conforming to standards isn't everything. (Standards often require thing that *never* catch on in actual use.)
An experienced author - such as Horowitz and Hill and their team - will have a good "feel" for what is easy to understand and what is not. What is customary in academic publishing is to use artists with little electronics experience, who tend to produce clumsy layouts with lots of momentarily misleading features. A of E has good intuitions about how to communicate in schematic diagrams. Keep it that way...
