cutting pdfs

I'm not an old fart, but I learned to cut pdfs years after college.

What to do, when something you've read and want to discuss with someone is an essay in a book old and unpopular enough that no one's bothered to put it up on its own on the internet?

What to do, when your friends and family will probably politely ignore the unsolicited mass of MBs you send over email?

This otherwise lazy person learned to cut pdfs to make it a more likely reality that they'll have friends to muck about in the fun-ness of such ideas. Or even say that it's dumb. Send me a thought, please.
