Abstract: The review of literature revealed that there is no uniform model or framework for evaluation of digital libraries. A generic model for evaluation of digital libraries and information services, called MEDLIS, is discussed in this paper. It proposes a generic framework for evaluation of digital libraries, which takes into account a number of pertinent issues related to a digital library service including the usage and usability issues, users' as well as service providers' perspectives, and most importantly, the business model of the concerned digital library. A multi-method evaluation strategy is proposed, which can be used for evaluation of any type of digital library.
