This ECAR research bulletin addresses a unique strength of higher education: its commitment to sharing ideas and promoting open access to knowledge. These values shape IT in higher education as well, as evidenced by many high-profile collaborations such as the Internet, Internet2, and open or community source applications such as Sakai and Kuali. Institutions work with one another on a broad range of projects and services including wide area networking, shared data centers, or disaster recovery. Some institutions share staff, while others outsource their IT operation to a fellow institution. Using findings from the 2007 ECAR study on IT collaboration, this bulletin explores the challenges that suggest that collaboration may become an even more prevalent strategy in the future.
