You’re not looking for a mailing list – they don’t publish that information. Just go to the admissions website, and they should have an email address for more information. Send them your home address.

So what you’re looking for are prospecti (plural of prospectus). Schools are a little loathe to send those out now since it’s cheaper putting everything online, so you may have to contact the office of undergrad admissions to request one. It’s possible to get some from departments you’re interested in as well if you ask their main office.

I would just go to the website of whoever you’re trying to contact, and if they don’t have a link about applying or more information, send an e-mail. It’ll even get to whoever can answer it.
