Level 4 "Research Level" indicates a collection that contains the "major published source materials required for doctoral study and independent research."
Level 3 collections provide "Study or Instructional Support," from basic through advanced. Levels 3a, 3b, and 3c are subdivisions indicating increasing collection depth. Level 3 collections support study from the undergraduate to the Masters degree, "as well as other specialized inquiries," which may be interpreted to mean preliminary dissertation level research at level 3c.
Level 2 indicates a collection of "Basic Information" resources, 2a being introductory and 2b advanced.
*The primary collection level indicators (0-5) are those of the RLG Conspectus. The chart above utilizes the WLN Conspectus definitions which include subdivisions to provide a total of 10 collection depth indicators. See chart on Columbia University Libraries web page.
