Study On Digital Resource Evaluation System

As the popularization and utilization of digital resources becomes an important part in building a digital library, how to make good use of the limited funds to purchase applicable, most needed digital resources and how to effectively evaluate the performance of these resources become the focus in digital library construction research. The evaluation of digital resources in libraries started from the late 1990s, with a view to get a better understanding of the ever increasing investment and its corresponding benefits. Because of the inadequacy of data and scientific methods, libraries cannot get to know real the utilizing situation and the users' opinions on this service and feel confused in making purchasing and serving policy. That is why an evaluation index system which can fully reflect the characteristics of digital resources on technicality, applicability and functionality should be built up to provide guidance on a systemic evaluation in libraries. Though a brand-new topic, it is a systemic project with practical meaning.This paper introduces the actuality of the development on digital resource evaluation nowadays, and tries to build up an evaluation index system by analyzing the existing one and exploring the issues which should be given much consideration in the process of the evaluation system construction.Part I provides an introduction to digital resource and its category and put forward the concept of digital resource evaluation;Part II introduces the research development on this issue both in China and abroad;Part III discusses related methodology from the aspects of Bibliometrics, netresource evaluation and international standard;Part IV introduces the existing evaluation index systems and makes a summarization of all the advantages and disadvantages of these systems;Part V analyzes the problems in the construction process of the system and puts forward the methods to improve it. Finally it leads to a new evaluation system which includes content evaluation, system function, using status,efficiency and related services and gives explain to the application matters of this new system.
