This document compares reference services at Kalamazoo College Library (KCL) and Grand Valley State University's Mary Idema Pew Library. Both libraries have learning commons that are less than two years old. At KCL, reference services operate from librarian offices during the week and a reference desk staffed by students evenings and weekends. The Pew Library does not have a reference desk and has research consultants and writing center staff handle most questions. Both libraries provide training to student employees but are still evaluating how the learning commons have affected reference services.
