through investigating both users' and librarians' perceptions of the relative importance of the major criteria governing the selection of digital resources, we attempted to develop a criterion weight framework for a library’s selection of digital resources, which can meet both the users' requirements and the library’s goal of developing digital collections. the respective weight of each specific criterion is decided through the analytic hierarchy process (ahp) method. the findings of this study indicate that, when assigning weights to the selection criteria, it is important to consult the opinions of a wide cross-section of people, especially the views of different users. as a result, the digital resource selection system characterized by the criteria weights can reflect more comprehensively the users’ requirements, and meanwhile it enables librarians' more rational selection of digital resources.
