Suppose you read in USAToday of an amazing response to a corporate leadership book written by the CEO of a large defense corporation that everyone's heard of, and that it's sold more than a quarter million copies.
Suppose further that one of the points of this book strikes a chord that prompts you to look through stuff you've collected over the years, and you find a book given you by one old mentor with almost exactly the same title (it's geared to the engineer, not the manager). It's an obscure book--thin, written during the last big war.
You look inside and all, yes, all the points are virtually the same (the occasional dash replaced with a colon), and, though you don't have the CEO's book, you can see that the ideas are basically the same, the number of points made is the same, and the points themselves are the same.
Is this plagiarism, and is it copyright infringement?
