The higher ed technology group Educause on Wednesday released its based on the results of its "Core Data Service Fiscal Year 2008 Summary Report,"  annual survey of 930 colleges and universities. This year's installment focuses on information technology trends on campuses between 2004 and 2008. Centralized IT funding rose, but only in proportion to enrollment and inflation. Outsourcing became more popular: In 2008, 70 percent of colleges used an external supplier for at least one IT function, and the use of homegrown systems decreased for all categories except library information systems. Colleges have increasingly turned to commercial vendors for learning management systems and e-mail clients, with a number of campuses considering dropping institutional e-mail addresses altogether, the report says.
