Putting in 'traps' to catch plagiarism didn't work for Fred L. Worth.
He deliberately added some 'made up' facts into his "The Trivia Encyclopedia" including:
"Columbo's first name was Philip"
When this appeared as a Trivial Pursuit question, he attempted to sue, but it was thrown out of court on the basis that many sources had been used to make the questions. http://www.triviahalloffame.com/columbo.aspx
I guess it is a case of: Copy one source - plagiarism; Copy many sources - research.
