I've actually created a Glossary to act as a handbook.
I work for a combined uni and vocational-level training provider and have had trouble previously trying to figure out a way to communicate all of the available policies we have to students and staff without providing a gigantic book to them or burying it off to one side. The policies are sorted in alphabetical order (currently) and I'm planning on including things like general terminology and other policies.
Main reason behind this as well is that our policies are provided as separate offline documents for compliance reasons and also because not all policies are relevant to all students. (For example, a policy about assessment will differ between the two as one is pass/fail, the other is not)
