In December of 2011, the A. T. Still Memorial Library at the A. T. Still University of Health Sciences was invited to be a beta test site for ClinicalKey, a major new point-of-care and research platform recently introduced by Elsevier. The advance marketing for ClinicalKey implied its use as a point-of-care-product for physicians. Over the past several years, library staff had been exploring an institutional subscription to UpToDate, so we decided to conduct a side-by-side trial of the two products and to survey participants about their experiences and preferences if the library were able to subscribe to only one of the two. Survey questions were designed to ascertain not only the participants' overall preference, but to provide detailed information to the library staff concerning the basis of this preference, including ease of access and use and the relative value of the two products in the students' didactic and clinical years.
