Inside Higher Ed reports this morning on Princeton University Press’s recent experience tracking pirated copies of its books.

For several months, Princeton had a staffer focused on identifying piracy sites with its books, and following up with “take down” notices that threaten legal action for keeping the books up. Some of the Web sites take the books down, but then others pop up. Most of these sites operate outside the United States and take advantage of countries with relatively loose copyright laws, at least as applied to digital publishing.
