I wrote an essay for a professor of mine, in which I cited a book he had written. As it so happens, the citation is based on my having obtained a (most likely) pirated PDF copy of the book. The text is quite expensive, not readily available anywhere (library, textbook store, or Amazon) aside from the publisher, and the subject matter is esoteric and poorly addressed in other papers. I am only citing less than 10 pages worth of material, mostly on definitions and problem formulation
I am going to be presenting this essay in front of the class, and my concern is that he will notice the citation of his book and ask the potentially uncomfortable question of "...so you have one of my books...?"
I'm wondering what I should do in this case. Should I simply remove all references to the problem texts and cited portions and pretend that nothing ever happened? Should I not do anything? Is the citation of a text that you pirated really a big deal in academia?
