Taking a step away from my indignant high horse for a moment, I do find it interesting that plagiarism and piracy of books has been around since the invention of the printing press. Initially, imitation in the Renaissance was seen as a compliment, a form of flattery, at least in art.
In the world of the cheaply printed piece, necessity and practicality were at the heart of imitation. Printers regularly used the same woodcut again and again--say, of someone being hanged--most likely for ease of use and to evoke a certain image or memory in the audience.
But over the next century or two, there seemed to be growing concern with the ability of printers to simply reset a piece and sell it for themselves. On occasion, advertisements to booksellers were created, informing them when a "sham" edition of a book had been created.
They would implore the bookseller to consider the nature of property; they also seemed to speak to the bookseller's sense of quality, by reminding them of the inferiority of the sham piece. For example, this next advertisement reminds the bookseller that "The sham edition has several mistakes and blunders, contrary both to sense and grammar."
In particular, I like the last line, which warns against those who would claim not to have known they were doing anything illicit: "This notice is given to prevent all persons from coming into trouble through ignorance."
In my next post, I will tell you what happened to one of these plagiarists...
