While libraries use sophisticated metrics to determine e-resources usefulness, impact and cost effectiveness, much of this reflects past usage. To elicit qualitative data, an open-source application that inserts a pop-up survey between a citation and its full-text was tested. Inspired by MINES for Libraries®, this pop-up survey aims to capture users’ real-time reasons for selecting a given resource. Join us to learn about the application, users responses to the survey and to discuss future uses.
