(Apologies if this isn't the place to ask, as I'm not a college student or independent researcher).
I am a secondary school student in Ireland currently working on a large project for a history class and the topic I have chosen is relatively obscure. The most thorough of the few books written on the matter seems to be currently out of print. I found a used copy for sale a while ago at an exorbitant cost, but I'm unable to find even that now.
Would it be okay for me to email the author to ask if he could direct me towards somewhere where I could find a copy of the book, or send me a pdf? I would be willing to pay, although I doubt I could afford the full price of the book originally which was upwards of $100.
