"One can find them if one looks; one doesn't need a book with chord charts."

Sorry, I meant the chords. The seven basic forms for the scales are as follows:

Take five frets. All of the notes are reachable with a a maximum of 1 shift of position. Take the lowest fret as the position, say fret 1, but it works for any position (until you run out of space toward the bridge). You can build scales starting from the notes on first, third and fifth frets on the low E and A strings and the first fret on the D string. That's seven scales. Do the same thing starting from the next fret (in this example, the second), and you have seven more scales. Since there are only twelve notes in the chromatic scale, two are duplicates.

The keys are F, G, A, Bb, C, D, Eb / Gb, Ab, Bb, B, Db, Eb, E.

The duplicates are Bb and Eb.
