Google is the search engine of choice for most Internet users. For a variety of reasons, librarians and other expert searchers do not always use Google to its full potential, even though it provides capabilities not possible in traditional bibliographic databases and other search engines. Applying expert searching principles and practices, such as the use of advanced search operators, information retrieval strategies, and search hedges to Google will allow health sciences librarians to find quality information on the Internet more efficiently and effectively. 相似文献

Google is the single largest driver of traffic to library Web sites and digital repositories, and librarians would do well to listen when the search giant reveals information about its practices or makes recommendations. Recently, Google announced that it would begin to favor Web sites that use the secure hypertext transfer protocol (HTTPS) in its search results rankings. HTTPS encrypts data transmission and one of Google's stated reasons for this change is to help make the Web safer and minimize data theft. Similar announcements by Google have sometimes been ignored by librarians, to the peril of the visibility and use of library products and services on the Web. 相似文献

The article reports on a systematic method of undertaking a literature search on the educational impact of being a young carer (16–24 years old). The search methodology applied and described in detail will be of value to academic librarians and to other education researchers who undertake systematic literature searches. Seven bibliographic databases and Google Scholar were searched between November 2015 and January 2016. Two and three concept search structures were compared, involving 28 search terms plus truncation variants. One hundred and eighty-one relevant articles were retrieved. Sensitivity, precision, and “unique articles retrieved” were used as metrics. Social Care Online and Google Scholar had the greatest sensitivity. As well as meticulous use of AND, OR, and bracket operators, the use of NEAR and NOT operators to increase precision were tested and are recommended as useful tools for conducting systematic searches. 相似文献

Expert searching in health librarianship: a literature review to identify international issues and Australian concerns 总被引：1，自引：1，他引：0
Lasserre K 《Health information and libraries journal》2012,29(1):3-15
Background: The traditional role of health librarians as expert searchers is under challenge. Objectives: The purpose of this review is to establish health librarians’ views, practices and educational processes on expert searching. Methods: The search strategy was developed in LISTA and then customised for ten other databases: ALISA, PubMed, Embase, Scopus, Web of Science, CINAHL, ERIC, PsycINFO, Cochrane Library and Google Scholar. The search terms were (expert search* OR expert retriev* OR mediated search* OR information retriev*) AND librar*. The searches, completed in December 2010 and repeated in May 2011, were limited to English language publications from 2000 to 2011 (unless seminal works). Results: Expert searching remains a key role for health librarians, especially for those supporting systematic reviews or employed as clinical librarians answering clinical questions. Conclusions: Although clients tend to be satisfied with searches carried out for them, improvements are required to effectively position the profession. Evidence‐based guidelines, adherence to transparent standards, review of entry‐level education requirements and a commitment to accredited, rigorous, ongoing professional development will ensure best practice. 相似文献

ABSTRACT Almost three years after Google Scholar's inception, only a third of Ohio Library and Information Network (OhioLINK) member libraries link to it from their Web sites. This article reports the results of a July 2007 survey of OhioLINK academic librarians, conducted to find out about their attitudes and current practices regarding promotion of Google Scholar. It compares the findings about placement of Google Scholar on Web sites and inclusion in library instruction with previous research, and includes recommendations for libraries about Google Scholar. 相似文献

AbstractThe dramatic increase in the use of the global network is examined through statistics and examples of the involvement of many countries. Despite the explosive growth of Internet use and contrary to the increasingly frequent characterization of the Internet as global, gaps are identified in the international coverage of the network. Evidence of the participation of librarians in the global network is sought through an analysis of subscriber lists for selected library-related listservs. Findings show that representation of librarians from a few countries is very high, while representation of librarians from most countries is low or non-existent. The value of the Internet and the potential role librarians can plan in this evolving environment are discussed. 相似文献

ABSTRACT This article examined the search functions for all individual EAD Web sites listed on the Library of Congress Web site in 2003. In particular, the type of search engine, search modes, options for searching, search results display, search feedback, and other features of the search systems were studied. The data analysis suggests that there have been some improvements for EAD finding aids within Web sites, but also that problems persist. In addition, the functionality of search systems on Web sites varied considerably and the advantages of EAD finding aids for hierarchical searching have not been fully realized. The article also offers observations about cooperative EAD projects, the issue of search queries, and the relationship between Google and EAD Web sites. 相似文献

ABSTRACT In this article Jenkins and Beall, librarians at Auburn University, have identified free Web sites for providing answers to business reference questions most frequently asked in academic libraries. The authors determined these questions by polling other business librarians, researching the topic on the Internet and in business literature, and drawing upon their business reference backgrounds. Web sites were selected by searching the Internet extensively, querying other business librarians and business faculty, combing numerous business academic library Web pages, and experience by the authors in answering business reference questions via the Web. The researchers sought answers and noted productive sites for each question. Jenkins and Beall expect this article will help other librarians determine the most useful Internet sites for answering business reference questions. They also hope this research will provide guidelines for librarians in developing solid lists of essential Web sites for business researchers. 相似文献

Abstract Organizing and evaluating information available to library patrons on the Internet is a constant challenge for librarians. Academic health sciences librarians faced this challenge in an innovative and collaborative way when trying to organize and evaluate web sites providing medical information. Their project, called HealthWeb, can serve both as a prototype for public librarians trying to organize sites in other subject areas, and as a resource for patrons looking for high quality medical information available on the Internet. 相似文献

Abstract Presently, eating disorders affect millions of people. Today, the media and the Internet are major publishing channels for consumer health information. Much research has found that the media may offer insufficient information on eating disorders. This research examines the quantity of adult consumer health publications on eating disorders in magazine articles and on the Internet in 1998 and investigates the effectiveness of Internet search engines. The results indicate that the resources found in popular magazines and on the Internet are not adequate, and that the Internet search engines are not effective in searching for information. 相似文献

Summary Increased student use of the Internet and declining reference desk statistics are factors encouraging academic reference librarians to look for new ways to reach patrons. Web-based customer contact center software gives librarians the tools to provide interactive, 24/7 reference service to Internet users. This article describes how the library at California State Polytechnic University, Pomona developed its live/web reference service. We discuss the factors that encouraged us to launch the service, the challenges that we encountered along the way, and examples of our experiences to date. 相似文献

Summary The objective of this article is to examine some of the valuable philosophical resources available on the Internet, especially for librarians who need to determine what resources to provide to faculty, students, and staff. Some main uses of the Internet for philosophical research are: accessing texts, using search strategies to examine the texts, reading and writing electronic journal articles, accessing information from encyclopedias and dictionaries, browsing through paths of interlinked Web sites, searching the Internet for sources, and participating in online discussion forums. This article examines the Internet as a source of primary and secondary texts, journal literature, research databases, reference works, specialized limited area search engines, organizational information, and discussion lists. The article ends with a philosophical reflection on the transformative effect of information technology on the growth of knowledge. 相似文献

ABSTRACT Search engine use is one of the most popular online activities. According to a recent OCLC report, nearly all students start their electronic research using a search engine instead of the library Web site. Instead of viewing search engines as competition, however, librarians at Binghamton University Libraries decided to employ search engine optimization strategies to make their Web site more visible on the search engine result pages. Although search engine optimization is used frequently by commercial Web sites, few libraries have attempted to optimize their own sites. This article describes Binghamton University's experiences in developing and implementing an optimization pilot project. The research presented in this article has importance for libraries who may be considering an optimization project for their own sites. 相似文献

Objective:In regard to locating clinical trials for a systematic review, limited information is available about how librarians locate clinical trials in biomedical databases, including (1) how much information researchers provide librarians to assist with the development of a comprehensive search strategy, (2) which tools librarians turn to for information about study design methodology, and (3) librarians'' confidence levels in their knowledge of study design methodology. A survey was developed to explore these aspects of how a medical librarian locates clinical trials when facilitating systematic reviews for researchers.Methods:In this cross-sectional study, a 21-question survey was sent to medical librarians via several email listservs during April 2020. Respondents were limited to librarians who make the decisions on search terms for systematic reviews.Results:Responses (n=120) indicated that librarians were often asked to search for various types of clinical trials. However, there was not a consistent method for creating search strategies that locate diverse types of clinical trials. Multiple methods were used for search strategy development, with hedges being the most popular method. In general, these librarians considered themselves to be confident in locating trials. Different resources were used to inform study types, including textbooks, articles, library guides and websites.Discussion:Medical librarians indicated that while they felt confident in their searching skills, they did not have a definitive source of information about the various types of clinical trials, and their responses demonstrated a clear need and desire for more information on study design methodology. 相似文献

ABSTRACT The “difficult” requests submitted by the research library users prove document delivery vendors could hardly replace interlibrary loan librarians. “Difficult” requests ask for the “grey literature” not traded commercially and not kept in libraries. They require the special attention and professional knowledge of the interlibrary loan librarian. Besides usual bibliographic and reference tools, the Internet, e-mail, and the search engines have to be employed to solve them. The help of those responsible for the production of the literature in question is significant. In tackling “difficult” requests, interlibrary loan librarians may further add value to their services by facilitating sharing between scholars or researchers. Five actual cases are presented to illustrate how the “difficult” requests were tackled and solved. 相似文献
