Another place to look


PRISM is UCalgary's institutional repository which manages, preserves, and provides access to the academic work by faculty, students, and research groups at the University of Calgary. Many types of materials can be submitted to PRISM including learning objects and OER, so it's another place you could look for UCalgary-specific OER.
