This study considered the development, awareness, adoption, and usage of digital library (DL) resources at the university level. To develop and implement a successful electronic library resource system, it is vital to review the success factors and identify the most important technological aspects of DL resources. Electronic library information technology was described and grouped into several categories that influence user satisfaction in a DL context. These are open access to information, the facility of access, uncomplicated interface design, high quality of the communication process, Internet performance, performance assurance service, ease of communication via social network, and patron-driven acquisition. With these important features of DL services, the simplicity of accessing online information and the performance of DL utilities have become of paramount importance. Several research works were therefore reviewed and evaluated to determine the usability of DL services; thereafter, the design of the DL discovery system was developed through Blacklight open-source software.
