The Registrar is the legally responsible book keeper for student records. The Registrar's office has the most complete information including high school recommendation letters and other pertinent application for admission materials. All changes to a student's record (e.g., registration, transfer credits, certification for graduation) must be recorded by the Registrar.
The Registrar makes some student records (e.g., transcript and on-line registration) available through a computer interface called Student Information Services (SIS). Training and certification for SIS is provided by the Registrar.
