The Hidden Traps in Reference Books

Cartographers and publishers often insert fake information into their work on purpose. These intentional errors act as copyright traps, allowing creators to catch anyone who copies their material without permission.

You might be surprised to find non-existent roads on a map or imaginary definitions in a dictionary. Known as mountweazels or trap streets, these inventions are purely legal safeguards. If a competitor produces a map that includes the same fake street, the original author has definitive proof of plagiarism. It is a brilliant way to protect intellectual property through creative dishonesty.
