This article presents the challenges and rewards of sharing research content through a discussion of Open Context, a new open access data publication system for field sciences and museum collections. Open Context is the first data repository of its kind, allowing self-publication of research data, community commentary through tagging, and clear citation and stable hyperlinks, and Creative Commons licenses that make reusing content legal and easy. The Nov-Dec 2007 issue of Educational Technology magazine is an entire special issue dedicated to "Opening Educational Resources." A series of articles in this issue highlight open educational models, including OpenCourseWare, Connexions and this piece on Open Context, co-authored by Sarah Whitcher Kansa and Eric Kansa.
