Wayne State University Libraries has been working on several projects aimed at better understanding library material usage using OCLC products and APIs. The library staff’s efforts have led them to develop a library dashboard, a visualization tool that allows staff to see how users access materials via ILLiad interlibrary loan. This tool allows library staff to see not only usage, but also the costs associated with journal interlibrary loans. These costs include copyright clearance fees and vendor-supplied document delivery fees.
