Staff at the desk should identify the University Department that the course is in and refer to the specialist assigned that department. OR In cases that the user is doing non-course related research, identify the University Department that the user is associated with, refer to the specialist assigned that department.
Staff at the desk may refer patrons by giving out business cards, but preferably only to students, staff and faculty of the University of Maryland. UMUC students should be referred to UMUC librarians and non-UM patrons can be told when the appropriate subject specialist is scheduled to work at the desk.
Anyone at the desk should feel free to give out a card, but please first make sure that the librarians on duty (if ones are scheduled) are unable to help the patron and that he/she does indeed need to consult with the subject specialist.
