Some libraries have created more tutorials than others, but here are all the PALNI schools with a Guide on the Side instance.
Academic and research libraries small and large are using Guide on the Side. Most libraries have guides teaching students how to use discovery layers or article databases. This page contains some examples of what libraries have produced so far.
Is your school using Guide on the Side? Have a great guide you'd like to show off? Let Ruth or Eric know! firstname.lastname@example.org
