Brad Frazer takes questions about the often-esoteric details of U.S. copyright law. For example, does registering a work published in an electronic format also cover later print versions? Yes, Frazer writes: "Except for sound recordings and derivative works like a screenplay (in which the words are changed), one registration of your copyright in the book as a PDF (or whatever the required Deposit Copy file format is) will cover multiple print formats of that same book."
