A Letter of Collaboration is an introductory, general, and non-binding agreement meant to initiate relations with a partner institution. It is essentially a "handshake" agreement to take steps in the future towards a more concrete program.  An LoC does not describe detailed collaboration commitments but merely lists areas of potential future collaboration.

As a result of its non-binding nature, no financial obligations should be included in a Letter of Collaboration.

A general LoC may be initiated by the partner institution or by OSU.
