The University of Colorado Boulder Libraries, a prominent advocate for Open Access within the University of Colorado System and nationally, has been supporting CU Boulder faculty, students, and staff since 2012 in the payment of author and/or article processing fees and charges (APCs) to support publication of CU-Boulder research in gold open access journals.Nationally, when academic libraries chose to support Open Access publication costs, it is often an effort to contribute to publication models that allow for worldwide, freely available access to research.This poster explores and analyzes data collected from the University of Colorado Boulder Libraries’ Open Access Fund from July 2012 to December 2015, illustrating the disciplines and demographics of participants, venues of publication, as well as begin to explore the implications of the cost of this program over time.
