Subject librarians (Liaisons) have assigned liaison duties affiliated with a particular subject area. Liaisons are responsible for a variety of duties including instruction and outreach. Each subject librarian is also responsible for a regular and ongoing program of collection assessment, improvement, and deselection, including monitoring the approval plan, making decisions on lost/missing item replacement, faculty requests, firm-order requests, serials, e-books, databases, audio-visual materials, and other formats as appropriate. Subject librarians are expected to solicit the involvement of faculty in all relevant content and collection management projects.
In addition to the liaison system, RLTS also has a "selection team" made up of three RLTS subject librarians and led by a coordinator. All decisions made by the Selectors Team are subject to final approval by the RLTS Head and Content & Collection Manager.
