ABSTRACTDiscovery tools are used in libraries to bring together books, articles, and other resources. Research has focused on user and librarian evaluation of these tools, but there are few evaluations of non-book and non-article sources. Discovery tools can also include metadata for local collections harvested through the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Creating these harvests can be time consuming for staff, so it is important for libraries to understand if and how patrons use these records. The University of Nebraska-Lincoln Libraries (UNL Libraries) harvests metadata from local collections into the Encore discovery tool. A study was conducted to analyze patron use of OAI-harvested records. This study analyzed usage data for harvested collections obtained from different discovery sources and referrals through Encore. Google Analytics was used to evaluate searcher behavior differences between content referred through Encore and other referrals. Although discovery through Encore did not result in high numbers of traffic, there is evidence that patrons who discover records through Encore take more time looking through records than patrons using other discovery methods. This increase in time is a measure of engagement and may be reason enough for libraries to consider adding OAI-harvested collections to their discovery tool. 相似文献

This study examines usage patterns of psychology e-books and equivalent print titles held in Texas A&M University (TAMU) Libraries collections. The authors sought to determine how well PsycBOOKS, a specialized subject-based collection, serves users' needs. Results support evidence-based collection acquisition and management decisions of books in print and electronic formats. Major findings indicate that PsycBOOKS is a critical and cost-effective resource supporting the TAMU user community and that hybrid print and electronic collections should coexist to support a variety of user information needs. 相似文献

FRBR, FRAD, and FRSAD models propose user tasks as a way to address and categorize functions that a catalog should support. The user tasks are not harmonized among these models, but to do that, they should first be fully understood and analyzed, especially “select” and “identify.” We decided to look at the FRBR user tasks from the perspective of interactive information retrieval (IIR). Several IIR models were reviewed and Ellis’ and Belkin's models were chosen for further analysis and interpretation of FRBR “select” and “identify” tasks. 相似文献

Collection development in public libraries is performed by one or more librarians who make use of a variety of selection tools. Computers and information systems are becoming increasingly important tools for selectors because they offer alternatives for assessing user needs, for gathering information about published materials, and for obtaining materials quickly. This paper describes a case study of twelve public library systems, the tasks they perform, and the sources they use in collection development. The selectors reported satisfaction with their jobs, increasing reliance upon information systems and electronic resources, and the need for system improvements to support selection for local collections in a publishing climate responsive to popular taste. 相似文献

ABSTRACT Digital libraries and collections are a growing facet of today's traditional library. Digital library technologies have become increasingly more sophisticated in the effort to provide more and better access to the collections they contain. The evaluation of the usability of these technologies has not kept pace with technological developments, however, and the end-user has in some cases been left behind. This research study evaluates the usability of digital collections created using the CONTENTdm Digital Collection Management System, a software system used by the University of North Carolina at Chapel Hill. Specifically, this study addresses the following questions: Does CONTENTdm meet users' needs? Is the interface sufficiently intuitive for them to use it? Is the experience of exploring digital collections using CONTENTdm satisfying to users? Employing usability testing techniques with actual-end users, this study attempts to assess the efficacy of the CONTENTdm public interface as well as user attitudes toward it. Ten participants from three user groups—faculty, library science graduate students, and the general public—performed eleven tasks designed to test the key functions of CONTENTdm-created collections and then answered a series of questions about their experiences. Key findings from this study indicate that while the included digital collections are useful and desirable to end-users, the interface generated by CONTENTdm can be confusing even for those who have considerable experience using the Internet. Results from this study may be used to improve this software system and add to the literature surrounding the usability of digital libraries in general. 相似文献

Search boxes providing simple keyword-based search are insufficient when users have complex information needs or are unfamiliar with a collection, for example in large digital libraries. Browsing hierarchies can support these richer interactions, but many collections do not have a suitable hierarchy available. In this paper we present a number of approaches for automatically creating hierarchies and mapping items into them, including a novel technique which automatically adapts a Wikipedia-based taxonomy to the target collection. These approaches are applied to a large collection of cultural heritage items which is formed through the aggregation of other collections and for which no unified hierarchy is available. We investigate a number of novel user-evaluated metrics to quantify the hierarchies’ quality and performance, showing that the proposed technique is preferred by users. From this we draw a number of conclusions as to what makes a hierarchy useful to the user. 相似文献

Mbooks are open-access, digitized books freely available on the Internet. This article describes the Auraria Library's experience of loading brief MARC records for Mbooks into its online public access catalog and looks at some of the issues that arose from the record-loading project. Despite the low quality of the records, librarians in Auraria Library thought that loading them into the catalog was advantageous because of the rich content in the collection and because many of the records could be improved using the global update functionality in the catalog. Making the records available through the catalog, as opposed to merely linking to the entire collection from the Library's Web page, was considered to be valuable because of the aggregation a catalog provides and because the Mbooks collection helped fill gaps in the Library's physical collections. As more open-access, digitized books become available, libraries will need to plan and manage how best to provide access to them. 相似文献

[目的/意义]信息搜索是人们常用的信息查询方法,目前搜索系统在查找事实型信息时支持效果较好,但是对人们以学习为目的的搜索功能还缺乏研究。"搜索即学习"（search as learning）是近年来交互式信息检索的研究热点,这类研究中将搜索看作学习的过程,并尝试对用户搜索中的知识学习进行评估,进而提出系统支持用户学习的功能优化建议。本文着重解决如何全面评估用户搜索前后的知识水平,为此类研究提供参考。[方法/过程]采用用户实验法,对用户搜索前和搜索后撰写的知识内容进行评估,提出综合数量与质量维度的用户知识评估方法,对用户在学习型任务搜索前后知识水平进行评估。数据分析阶段采用统计方法来验证用户搜索后与搜索前的知识水平差异。[结果/结论]研究发现,用户在知识数量上的表现随着搜索的完成而变得更加全面和深入,在知识点数量、知识面数量、知识面广度和知识面深度上都有显著的提升。同时,在搜索后产生了专业度较高的知识面。对于搜索前较模糊的某些概念,在搜索后表达得更清晰明确。在质量上,搜索后绝大多数的用户都在知识的相关性、分析程度及用户观点的提出方面有所提升。 相似文献

With the increasing mobility of the population, Electronic Medical Records (EMRs) become a promising opportunity for governmental investment to many countries. An EMR project usually involves a huge grant and needs tight control of the output. However, most measuring tools for the quality of paper-based medical records placed a focus on data format and compliance with law which may not be sufficient and adequate enough in measuring the EMR's quality. The purposes of this study are to firstly develop and validate an instrument for measuring the quality of EMRs using 217 physicians and nurses at 25 hospitals and then examine the relationship between the EMR's quality and user satisfaction. Four first-order constructs of EMR quality were identified, namely data content quality, data model quality, information quality, and knowledge quality. Only the quality of data content and information impact user satisfaction significantly. Based on the research findings, implications and limitations are discussed. 相似文献

Metadata Quality Control in Digital Repositories and Collections: Criteria,Semantics, and Mechanisms
This article evaluates practices on metadata quality control in digital repositories and collections using an online survey of cataloging and metadata professionals in the United States. The study examines (1) the perceived importance of metadata quality, (2) metadata quality evaluation criteria and issues, and (3) mechanisms for building quality assurance into the metadata creation process. The survey finds wide recognition of the essential role of metadata quality assurance. Accuracy and consistency are prioritized as the main criteria for metadata quality evaluation. Metadata semantics greatly affects consistent and accurate metadata application. Strong awareness of metadata quality correlates with the widespread adoption of various quality control mechanisms, such as staff training, manual review, metadata guidelines, and metadata generation tools. And yet, metadata guidelines are used less frequently as a quality assurance mechanism in digital collections involving multiple institutions. 相似文献

Authority control is discussed from two viewpoints: The need for bibliographic records relating to a name to be brought together under one form of the name; and the need for cross references to direct a user to a heading from variant forms of the name. Data from two research projects that support the need for choosing one form of name are summarized. The author's study of user requests that resulted in no "hits" in an online catalog is described. Data are given to show that for only 6.4% of these requests would our current methods of cross referencing in authority records have been helpful, and that two system programs would have given much greater assistance. 相似文献
