Speaking as a university professor, I would look up the names of professors teaching compilers or related classes at various American universities, and send them an e-mail with a link to your site. Offer them a freebie if they are interested in using it in a class or sharing it with their students.

This will annoy some of them, but if so, they will have forgotten about it fifteen seconds later, so I don't think it matters a lot.

You might offer free copies to any class (i.e., the students too) that uses it until it becomes more established.

Keep in mind that a lot of university professors are fed up with the traditional publishing model (see http://www.thecostofknowledge.com) and will be naturally sympathetic to you.

Keep the e-mail brief. No HTML. A lot of these people use Pine :)

Good luck!
