Quality assessment in digital libraries

The services of digital library is one of the main differences which they had with traditional ones. However, in some definitions given by experts, they emphasizes this as an indicator; therefore, despite the adoption of measures to set up digital and network -based services, evaluating them and evaluating the extent to which they are successful in their own right, is one challenges of this field. Therefore, it is necessary to present models for assessing and optimizing existing models for the evaluation of digital libraries, and the other mechanisms should be used to implement them.
The book is intended to familiarize the reader with the evaluation models of digital library service and present the content to audience, but in a general impression it can be said that it failed in this aim. However, more judgments will be made by the reader.
