Purpose Usability, functionality, and accessibility testing of digital library information services and products is essential for providing high quality services to users. This paper aims to detail a long term, evolving effort to develop meaningful evaluations for assessing digital libraries.Design/methodology/approach A multi year study to determine appropriate evaluation techniques, tools, and methodologies for the Florida Electronic Library (FEL) and other digital library efforts. The evaluation protocols and approaches were designed iteratively over time through assessment efforts with other digital library initiatives and with multiple versions of the FEL. The research described in this paper relies on a combination of functionality, usability, and accessibility evaluation strategies applied iteratively to assess libraries from the perspective of patron needs.Findings By combining these three methodologies, the researchers found that they were able to create a rich and robust evaluation of digi.
