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

SUMMARY Buoyed by its brand name, Google News has grown from its beta stage into a popular news site with a significant share of the Internet market for “Current Events and Global News.” The success of Google News raises questions about the nature of news and even the desirability of Google's presenting news. Where does Google News fit into the myriad news resources available on the Internet and in libraries? How does Google News work? Is Google News an effective source for news research? How will Google News stand up to its competition, in particular a new wave of community news sites? 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

ABSTRACT The Google Book Search Library Project has partnered with an array of impressive libraries, including Harvard University, the University of California System, University of Michigan, and the New York Public Library. The reasons for collaborating with Google to further book digitization are different for each library. Moreover, the exact way in which these libraries will use their own digital copies has yet to be decided for many of the libraries involved. While the Google Book Search Library Project remains controversial, the Google library partners are seizing an unprecedented opportunity to amplify the scale of their pre-existing digitization initiatives. 相似文献

Dissertations can be the single most important scholarly outputs of junior researchers. Whilst sets of journal articles are often evaluated with the help of citation counts from the Web of Science or Scopus, these do not index dissertations and so their impact is hard to assess. In response, this article introduces a new multistage method to extract Google Scholar citation counts for large collections of dissertations from repositories indexed by Google. The method was used to extract Google Scholar citation counts for 77,884 American doctoral dissertations from 2013 to 2017 via ProQuest, with a precision of over 95%. Some ProQuest dissertations that were dual indexed with other repositories could not be retrieved with ProQuest-specific searches but could be found with Google Scholar searches of the other repositories. The Google Scholar citation counts were then compared with Mendeley reader counts, a known source of scholarly-like impact data. A fifth of the dissertations had at least one citation recorded in Google Scholar and slightly fewer had at least one Mendeley reader. Based on numerical comparisons, the Mendeley reader counts seem to be more useful for impact assessment purposes for dissertations that are less than two years old, whilst Google Scholar citations are more useful for older dissertations, especially in social sciences, arts and humanities. Google Scholar citation counts may reflect a more scholarly type of impact than that of Mendeley reader counts because dissertations attract a substantial minority of their citations from other dissertations. In summary, the new method now makes it possible for research funders, institutions and others to systematically evaluate the impact of dissertations, although additional Google Scholar queries for other online repositories are needed to ensure comprehensive coverage. 相似文献

Continuing education is vital for new librarians to gain skills and knowledge beyond library school. Professional development offered free in an online environment is often the best option for staying current on the issues and trends necessary for young librarians to grow and flourish. This paper presents a case study of an online professional development series for new librarians implemented by the Online Programs Committee of the American Library Association's New Members Round Table. 相似文献

This article summarizes published documents on metadata provided by Google for books scanned as part of the Google Book Search (GBS) project and provides suggestions for improvement. The faulty, misleading, and confusing metadata in current Google records can pose potentially serious problems for users of GBS. Google admits that it took data, which proved to be inaccurate, from many sources and is attempting to correct errors. Some argue that metadata is not needed with keyword searching; but optical character recognition (OCR) errors, synonym control, and materials in foreign languages make reliable metadata a requirement for academic researchers. The authors recommend that users should be able to submit error reports to Google to correct faulty metadata. 相似文献
