I know some of these links are on the blog already, but here is a little more info:
First you'll want to check out Harrisburg University's form 990s. The Form 990 is an annual reporting return that certain federally tax-exempt organizations must file with the IRS. It provides information on the filing organization's mission, programs, and finances. These are public documents and are available for free at Guidestar.org.
You can find lots of good info from The Nation Center for Education Statistics. Harrisburg University's specific information is available here.
You can find specific data on Higher Education at the Pennsylvania Department of Education website.
You can also find data about accreditation from the Middle States Commission on Higher Education. Harrisburg University's specific information is here.
