A LibGuide is a research guide created for specific courses, classes or subjects. LibGuides are created by the librarians in collaboration with faculty. Many faculty bring their classes to the Library to introduce them to a LibGuide created for a class or a specific assignment.
If your instructor does not have a LibGuide, why not suggest that he create one! They make research much easier by pointing you to specific databases that contain authoritative and reliable sources of information.
See the Library's homepage for a link to the LibGuides (arranged by subject on the left side of the page).
