Guide was used to collect reading lists and links and give examples for class. Advantages over the LMS were that changes to the guide went to all course sections and students could continue to use the guide after they lost access to the class in the LMS.
My quick-and-dirty training video for GPC Librarians as we were transitioning from LibGuides v.1. Note that some of the instructions (e.g. not to use the Internal Guide Type) are related to GPC's guide practices and may not apply elsewhere.
