Questions range from how to upload a document with a learning management system, to how to use software and hardware, to more complex questions about how to locate and research articles for term papers. The literature reviewed provides a glimpse into the historical roles, current roles, as well as possible new roles that libraries and librarians may play in the future. This article identifies various library services that are essential to distant learners and distance education settings, and will explain how librarians and libraries are providing these services online.
