Digital library research has developed over the past decade, but little has been done on the identification of evaluation criteria, especially from users' perspectives. This article identifies users' criteria and applies them to the evaluation of existing digital libraries. Forty-eight subjects were instructed to develop and justify a set of essential criteria for the evaluation of digital libraries. At the same time, they were requested to evaluate existing digital libraries by applying the criteria that they were developing. A compilation of criteria developed by participants show that usability and collection quality were the most important criteria for evaluating digital libraries. Service quality, system performance efficiency, and user opinion solicitation were also deemed essential criteria. The author further compares digital library evaluation criteria identified by users and researchers and applied in previous research. The article reveals problems in current digital library design and development, discusses suggestions for improving digital library design, and presents areas for further research. 相似文献

Professional literature about the assessment of digital libraries reflects a growing interest in both improving the user experience and in justifying the creation of digital collections to multiple stakeholders. This article explores some of the key themes in digital library assessment literature through a review of current literature (2004–14) gathered from both scholarly and popular resources online. The majority of scholarship about digital library assessment utilizes usability testing and Web statistics for data collection, while studies about altmetrics, the reuse of digital library materials, cost benefit analysis, and the holistic evaluation of digital libraries are also present in the literature. Exploring the literature about digital library assessment allows libraries to create effective and sustainable evaluation models based on the successes and shortcomings of previously completed projects. 相似文献

The recent development of personal digital collections systems on museum websites has prompted researchers to examine the motivations and expectations of museum visitors as they interact with those systems. Results from an online survey completed by visitors to six different museum websites show that users of personal digital collections systems are primarily motivated by a desire to create simple collections of objects and images, and are less influenced by the more complicated features museums have implemented to encourage user participation. The significance of these findings is explored through a discussion of user expectations and motivations with respect to creating personal digital collections, and an attempt is made to reconcile some of the disparities between the perceptions of survey respondents and the experiences of museum professionals developing and implementing personal digital collections systems. 相似文献

Information professionals and librarians have been studying, discussing, and developing digital libraries for more than two decades, but understanding ultimate use of images from digital libraries remains a mystery for many of them. Most articles written on digital library use focus on users’ search retrieval needs and behavior. Few mention how digital library patrons use the images they request. Like many digital libraries, archives, and special collections, the University of Houston Digital Library makes high resolution images available to its patrons. Image delivery is achieved by an automated system, titled the Digital Cart Service. An unexpected benefit of the Digital Cart Service is the reporting mechanism that produces data that includes intended use information. This article discusses the analysis of this data to determine why images were used, what products were created from the images, and what implications this has on digital library management. The authors believe that answering these questions creates an environment in which digital library innovators can better promote and design digital libraries, and describe and select the content in them. 相似文献

One way to promote the relevancy of an academic law library is to create a special collection that generates interest in the patron base; a popular collection is a viable way of reinventing a law library's image in the hearts and minds of the law school community. Popular collections have been championed by general academic librarians because they promote reading and literacy, the use of the library as a place, and such collections represent the shift toward a user focused library model. Using data collected from interviews and analysis of collection development policies this article presents models of popular collections currently in use at academic law libraries, as well as considerations for the creation of such collections. 相似文献

Measuring the value and impact of health library and information services: past reflections, future possibilities 总被引：1，自引：1，他引：0
Marshall JG 《Health information and libraries journal》2007,24(Z1):4-17
Objectives: To summarize the context, history and results of research studies conducted on the value and impact of health library and information services by the author since 1975 and to use this as a basis for examining ongoing developments related to evaluation research. To provide a comprehensive bibliography of library value and impact studies. Methods: Literature review and background based on personal involvement in the studies under discussion. Results: The author's studies demonstrate an ongoing evolution of value and impact studies since the mid‐1970s. In health sciences libraries, the approach taken to measuring value and impact has been strongly influenced by the type of research being conducted in the health sciences field as a whole. As a result, health sciences library researchers have become early adopters of methods that incorporate outcome and impact measures and rigorous research designs, and the concept of evidence‐based library and information practice. The paper recommends that a range of research approaches from various disciplines be used to guide future evaluation research. Conclusions: Value and impact studies will continue to be important resources for evidence‐based practice as health information professionals deal with evolving user needs and new ways of delivering information to a variety of audiences. 相似文献

What is lacking from the literature and practice of library print collection assessment is a mathematical function that can integrate variables and quantify the overall measurement of the collection as a final score for the library science practitioners and administrators. The study uses the information entropy to explain a mathematical procedure on how to define variables from the regular circulation statistics. Based on the assessment concepts of circulation statistics and user behavior, the study explores to develop mathematical functions and proposes a Collection-User Suitability index to quantify the suitability measurement of the overall collection and the user intention. The study then considers the extreme conditions to validate the functions and verifies the application of the function via empirical and simulated data. Finally, the authors developed a computing tool and uploaded it to GitHub for free access based on the study's results. It is hoped that library science practitioners and administrators can utilize the mathematical function. 相似文献

SUMMARY This article proposes that a viable approach archivists might consider to meet increasing demands for access to digital images with functional presentation tools is to develop a reciprocal partnership with a digital library. The University of California's experience with the federation of licensed and UC-owned digital image collections is summarized to illuminate core issues related to collection development, system functionality, and patron usability. The resulting UC Image Service is then examined against a backdrop of comparable digital imaging projects with reflections on strategies and intersections. The range of business models and approaches to digital image collection access and developing image management and presentation tools highlight the unprecedented opportunities digital technology provides for moving archives towards an integrated environment through collaborative action. 相似文献

This study examined the use of academic libraries by academic sponsored researchers in the social sciences at five universities in the greater Boston area. It provides information about researchers use of the library during the proposal development and research stages; it inquires into other information sources employed by the researchers; and it collects data about the types and ages of information materials used in support of the respondent's research projects. Analysis of the responses indicates that for the majority of the researchers, the library was used between one and five times during their proposal development work but that the resources of the library were not a factor in the development of their research proposals. While the researchers indicated that they had used or expected to use their campus libraries as well as other libraries during the course of their research, they also expected to obtain research related information from other sources. They ranked their personal collections first in importance as the place they turned to for information materials in support of their research activity, with their campus library or libraries ranked second. 相似文献
