Abstract 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

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

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

This article reports a survey on the use of Internet services and resources in the engineering colleges of Punjab and Haryana states of India. Data were collected by using a questionnaire and follow-up interviews with Internet users, i.e. teachers and students of engineering colleges. The response rate was 80.8%. Results showed that all the respondents make frequent use of the Internet because they have access either at college or at home. The survey revealed that the majority of the respondents, i.e. 65.6%, access the Internet from college or their workplace. More than 75% of the respondents use the Internet services mainly for educational and research purposes. Google and Yahoo search engines are found to be more widely used than other search engines. More than 70% of the respondents feel that the Internet is useful, informative, easy to use, inexpensive and time saving. 相似文献

Adding the external variables of satisfaction and loyalty to Fred Davis' technology acceptance model (TAM), this study examined the extent to which graduate students perceived Google Scholar to be a resource that is useful and easy to use. A survey of 1141 graduate students at the University of Minnesota asked questions exploring their perceptions of Google Scholar as part of their research process. Seventy-five percent of survey participants had used Google Scholar at least once before, and a statistical analysis of the responses found that perceived usefulness, loyalty, and, to a lesser extent, perceived ease of use, were positively and significantly related to the graduate students' intended use of the information resource. This research showed that TAM is an applicable model for predicting graduate student use of Google Scholar, which can help academic librarians seeking to understand graduate student acceptance of new information sources. Additionally, this study provides information about how librarians might best promote Google Scholar and other library resources to graduate students. 相似文献

As more job searchers use the Internet and on-line services, librarians and career services professionals will play a greater role in educating clients about the ethical implications of an electronic job search. In this study, "electronic privacy" will be defined, and laws which govern electronic security as well as reactions to those laws will bc reviewed. Corporate policies on employee electronic accounts will be discussed. Technological methods being used to ensure confidentiality and privacy will be examined, andthe role and responsibility of career services professionals and librarians in training clients on an ethical job search will be addressed. 相似文献

This article provides a case study of how the University of Nebraska College of Law and Schmid Law Library use “buttons” to manage Law College faculty members’ and librarians’ online presence. Since Google is the primary search engine used to find information, it is important that librarians and libraries assist Web site visitors in finding relevant information about faculty members at an academic institution. Easily identifiable buttons allow visitors to navigate to faculty scholarship in the University of Nebraska-Lincoln Digital Commons, SSRN Web site, or both, in an academic service such as lessons from the Center for Computer-Assisted Legal Instruction and in social software sites like Twitter, Facebook, or LinkedIn. The case study includes (1) how the project was implemented, (2) the feedback and results of a survey, and (3) an analysis of Web site statistics, clicks, and links data gathered via Google Analytics. This project was a partnership between the Law College Communications Department, Law College Administration, and the Law Library, involving law faculty, staff, and librarians. The buttons project was considered a successful venture by participating faculty members; it also provided an opportunity for face-to-face conversation between faculty members and librarians about digital scholarship and social media in the academic environment. 相似文献

This article critically examines four Google search products (Google Advanced Search, Google News Advanced Search, Google Books Advanced Search, and Google Advanced Scholar Search) and shows how each uses metadata to enhance or improve search results. In addition, the article shows how metadata can increase search precision and recall in information discovery systems. From a library perspective, this article analyzes some of the metadata-enabled features of Google's advanced search pages and compares these features to those found in a typical online library catalog. From a serials perspective, Google News Advanced Search demonstrates how Google indexes news websites, sites that are essentially continuing resources. As Google incorporates more and more metadata functionality into its advanced search pages, they increasingly begin to function more like online library catalogs and less like search pages found in a traditional Internet search engine. The simple search box has many limitations, and like libraries, Google is increasingly creating and offering metadata-enabled search features that improve search precision and recall in its products. 相似文献

Google's initiative to scan and add book content into its search engine has resulted in much praise and protest. Changing its digitization project's name from Google Print to Google Book Search and adding information to its site did not keep Google out of copyright court. However, publicity surrounding this project has spawned renewed interest in book digitization projects, with collaborative efforts quickly growing. This article will look at Book Search's history, highlight how it has been altered along with its name, and point out other interesting book digitization projects that Book Search has spawned or recently brought into the limelight, such as those associated with the Internet Archive. 相似文献

OBJECTIVES: The aim of this study was to assess Internet connections and information technology skills of public health workers in the Midwest. METHODS: A questionnaire was mailed to 713 local health departments (LHDs) in the ten states of the Greater Midwest Region. RESULTS: Three hundred forty-four LHDs (48%) responded. Overall, 85% own a computer that would allow Internet access. Half provide Internet access to some or all staff. Of these, two-thirds use e-mail and half search the Web. One-half are linked to the State Health Department, and 30% are linked to other local health departments. Over half use CDC-Wonder; less than 20% search MEDLINE. Two-thirds of the respondents expressed an interest in MEDLINE training, and three-fourths are interested in learning more about the Internet. Sixty-nine percent of respondents planned to enhance electronic communication capacity within the next year. CONCLUSIONS: Public health practitioners need timely, convenient access to information to aid them in improving the health of the American public. A majority of public health departments in the Midwest are technically capable of connecting to the Internet. This technological capability, combined with an expressed desire by public health agencies to have workers become computer literate, suggests an important role for health sciences librarians. 相似文献

While the role of the librarian as an expert searcher in the systematic review process is widely recognized, librarians also can be enlisted to help systematic review teams with other challenges. This article reviews the contributions of librarians to systematic reviews, including communicating methods of the review process, collaboratively formulating the research question and exclusion criteria, formulating the search strategy on a variety of databases, documenting the searches, record keeping, and writing the search methodology. It also discusses challenges encountered such as irregular timelines, providing education, communication, and learning new technologies for record keeping. Rewards include building relationships with researchers, expanding professional expertise, and receiving recognition for contributions to health care outcomes. 相似文献

Googlitis, the overreliance on search engines for research and the resulting development of poor searching skills, is a recognized problem among today's students. Google is not an effective research tool because, in addition to encouraging keyword searching at the expense of more powerful subject searching, it only accesses the Surface Web and is driven by advertising. American higher education unwittingly fosters the use of search engines in research by emphasizing results rather than process. Academic librarians emulate teaching faculty in their reliance on lectures, and their course-related instruction is limited in its effectiveness because it is constrained to one-shot, lecture-driven sessions. A more effective way to teach research is to collaborate with faculty via problem-based and project-oriented learning tasks that incorporate authentic discipline-specific information finding and critical thinking into assignments. 相似文献

Making scholarly information visible to web search engines is an ongoing challenge, and undergraduate research is no exception. Using a sample of award-winning undergraduate history papers and journals, the authors searched Google, Google Scholar, Microsoft Academic, and the authors' institutional repository to gauge the difficulty of locating these works. Given that many of these works were not easily found, results suggest that libraries and their institutions could be doing more to increase the discoverability of undergraduate research. Based on the success stories observed in this study, we offer strategies to libraries and librarians for increasing the visibility of undergraduate student research. 相似文献
