Plagioija on varas

näin todettiin vuonna 1931 kirjassa Plagiarism: the "Art" of Stealing Literary Material (by Maurice Salzman). Kirjassa on Ellis Parker Butlerin kirjoittama artikkeli Plagiarists are Thieves. Tässä suora lainaus Butlerin tekstistä, artikkeli on julkaistu sähköisenä täällä:

"The Thief

A plagiarist is a thief and he knows he is a thief. This is so true that it is only necessary to ask a plagiarist to explain why he is not one, and he will involuntarily tell you he is one. He invariably gives himself away. His explanations are so full of holes and "becauses" that you can see right through them into the thieving heart of him. A thief talks like a thief."
