Regarding the purchase of Leanpub ebooks, we don't have any special arrangements for universities, but we do support group purchases, which universities often use.

When someone at a university wants to buy an ebook for a group of students or faculty, they make a multi-copy purchase of the ebook, and then distribute the purchase tokens we provide to their students or faculty according to these instructions:
