Scoped negative, 1919 US trade advice. Neither Chapter XVII nor Chapter XXI mentions copyright, plagiarism, theft, piracy or protection: 0 hits in the chapter text. The nearest practices in Ch. XXI (one firm at a time, a record of each script sent, a clean fresh copy rather than a carbon, caution about agents) are not presented as protection. Ch. XXI does not tell the writer to keep a copy; Ch. VI and XII, outside the assigned chapters, do. The book's plagiarism and copyright passages are elsewhere (see C3-B238-S62-03). No legal conclusion is drawn.

No legal conclusion is drawn.

Curator qualifications: The protection negative is scoped to two chapters, and the worker also reports 79 hits elsewhere in the book. Carbons in Ch. XXI concern what to send; Ch. VI is where keeping a copy is advised.
