医学个性化书目情报服务机制探讨

由于从事医学专业领域活动的多样性,专业读者与非专业读者、本单位读者与外单位读者、本地读者与远程用户在医学书目情报需求目的、需求类型、需求层次及需求行为均存在差异。为满足读者个性化书目情报需求,医学图书馆要提升本地资源与远程资源相结合的文献保障能力、Web 2.0支持下的书目情报技术服务能力、具有医学与信息管理背景的专家服务能力、医学书目情报深度知识服务能力。个性化医学书目情报服务策略包括:知识提供与知识获取技能相结合的策略、多渠道书目情报交流相结合的策略、需求驱动书目情报配置的策略、专家服务推动公共服务的策略。     

The Future of the Past: Archaeology and Anthropology on the World Wide Web

In the final scene of Raiders of the Lost Ark, a crate containing the object of Indiana Jones' quest is wheeled into an immense warehouse for indefinite storage and questionable research access. Unfortunately, this fate is not all that far from reality. Collections of archaeological and ethnographic materials ranging from stone axes, broken potsherds, and carved monuments to baskets, ceremonial masks, and skin canoes have been held by museums collections since the Renaissance. However, their inestimable value and unique conservation and curatorial requirements often conspire to remove them from the reach of all but the most diligent scholars. The potential of the Web to enhance the quality of research on archaeological and ethnographic collections is enormous. This paper will examine ways that one can use the Web to enhance research and improve access to a variety of materials; while there are many other resources for archaeology available on the Web, this paper focusses on museum-related sites. It will also explore the potential of the Web for innovative research strategies. Digitization of catalogs, associated documents, and images to help one locate and study collections and specific artifacts are just one approach. Others include the connection of devices to the Web, such as cameras and microscopes, the creation of virtual reference collections, and the establishment of research networks that will enhance the identification and analysis of material culture. This paper will also consider the role the Web could play in issues of cultural property, contributing to and in many ways intensifying ongoing debates of ownership, curation, conservation, and repatriation of sensitive materials.

Comparison of three web-scale discovery services for health sciences research

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.     

Helping patrons find locally held electronic resources: An interlibrary loan perspective

The University of North Texas Libraries provide extensive online access to academic journals through major vendor databases. As illustrated by interlibrary loan borrowing requests for items held in our databases, patrons often have difficulty navigating the available resources. In this study, the Interlibrary Loan staff used data gathered from the ILLiad interlibrary loan management system to investigate why patrons request locally available materials. This study resulted in recommendations for the Libraries' linking strategies in EBSCOhost databases. Several user education needs were identified and communicated to the Libraries' Subject Liaisons.
