Research on publication and citation patterns generally focuses on prolific or highly cited authors or on highly ranked programs. This study investigates the work and influence of a cross-section of library and information science (LIS) researchers at various stages of their academic lives, using a random sample of faculty members at programs accredited by the American Library Association. The analysis shows that the number of publications increases steadily as faculty rank advances. Assistant professors publish more conference papers and fewer journal articles, a pattern that is reversed with associate and full professors. Researchers used Web of Science® and Google™ Scholar to determine the influence of the publications. Web of Science reported no citations for most LIS faculty publications. With its broader scope, Google Scholar located more citations and revealed that the works of professors are cited significantly more frequently than publications by assistant or associate professors. When faculty profiles are compared by type of program, faculty members at schools granting doctoral degrees publish significantly more than their counterparts at schools where there is no doctoral program or where the doctoral degree is offered jointly with other academic units. When the comparison is made across ranks, full professors publish significantly more than faculty members at other ranks. There is no significant difference between assistant and associate professors. 相似文献

A methodology for constructing academic terminological and publishing structures using the Google Scholar search engine is presented. These structures are formed for the classical universities of Kharkiv and Skopje based on the example of basic environmental terms of a general nature that are distinguished in English-language publications. The environmental theme is more actively studied at Kharkiv National University. The first publications produced by the researchers of this university in the considered area of science were written in the early 1980s. An analysis of the most-frequently cited publications that contain the selected environmental terms shows that such publications are often a result of the work of an international team of authors. This is of great importance for the development of journal strategies and policies. By using Google Scholar, one can find significantly more publications on the website of Kharkiv University compared to that of the University of Skopje, due to the electronic open access archive system of publications at Kharkiv University. The frequency of occurrence for publications that contain selected environmental terms is higher in the case of the University of Skopje due to the fact that the publications of this university are poorly represented on the web and also because of their predominantly English-language character. 相似文献

This study seeks to explore institutional repository, social networking, and bibliographic databases of scholarly communication in Nigeria. Six institutional repositories (IR) were selected and five leading authors had their works manually crosschecked in two citation indexes and self-archived in social networking sites. The results reveal that faculty members have embraced self-archive on academic social network platforms, while their records in the IR do not reflect this. The study recommends Universities' management to implore academics to self-archive their publications into their IR, while the libraries too could search bibliographic databases and social network sites to update their respective IR platforms. 相似文献

The literature shows that students are more likely to begin their search via Google, as it is perceived to be easier and more accessible than other databases or publisher platforms. The invisible web, specifically publisher platforms, is sometimes too difficult for students to access; there are also suggestions that Google Scholar in particular may outperform other paid-for databases. The ease of access and the somewhat misguided notion that Google Scholar has more reliable information than that provided by libraries makes search engines all the more attractive. This culture of searching using a single search box is reflected in the increase in the number of libraries opting for single resource discovery systems such as Summon or Primo, which use a single search covering all the library holdings. The findings suggest that whilst Google Scholar can perform well in some circumstances, it performed only moderately well when compared with LISTA and Summon – the single resource discovery system tested. It was the least successful resource in terms of precision when compared with LISTA, Summon, Emerald and Sage. However, the simplicity of search engines begs the question: will databases and publisher platforms become obsolete? The study concludes that subject specific databases are more effective than search engines, but the complexity of accessing the invisible web is hindering their popularity. 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

As one of the largest active academic social networking sites, ResearchGate (RG) has been utilized by scholars to share publications, seek collaborators, communicate work in progress, and build scholarly reputation. This study collects data from RG users from 61 U.S. research universities at different research activity levels, as categorized by the Carnegie Classification of Institutions of Higher Education, to examine the impact of institutional differences on RG reputational metrics. The results confirm that RG is a research-oriented academic social networking site that closely and realistically mirrors the research activity level of institutions. With an increase in the research activity level of a university, its affiliated RG users tend to have higher RG scores, more publications and citations, and more profile views and followers, while the average number of reads of their publications and followees tend to be lower and fluctuant. In addition, RG users primarily follow others from institutions of a higher research activity level, forming virtual social networks centered around esteemed institutions. The study suggests academic social networks can serve as indicators in evaluation of research activities among research institutions, and such sites can be helpful and credible for acquiring resources, keeping informed about research, and promoting academic influence. 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

The availability of web search engines offers opportunities in addition to those provided by bibliographic databases for identifying academic literature, but their usefulness for retrieving research is uncertain. A rigorous literature search was undertaken to investigate whether web search engines might replace bibliographic databases, using empirical research in health and social care as a case study. Eight databases and five web search engines were searched between 20 July and 6 August 2015. Sixteen unique studies which compared at least one database with at least one web search engine were examined, as well as drawing lessons from the authors’ own search process. Web search engines were limited in that the searcher cannot be certain that the principles of Boolean logic apply and they were more limited than bibliographic databases in their functions, such as exporting abstracts. Recommendations are made for improving the rigour and quality of reporting studies of academic literature searching. 相似文献

This paper presents qualitative findings about the search behaviors and research habits of students interviewed at six college and university campuses in the US. Our findings suggest that students’ strategies are influenced by both their non-academic search experiences as well as the broader academic context of their research tasks. Their behaviors suggest an on-going negotiation of these influences, evidenced by the ways they incorporate Google into their research strategy while still closely adhering to faculty instruction for using library resources. Students bring a strong sense of self-reliance to the research process, yet they still experience many barriers and pain points accessing library resources. We have included recommendations for librarians and faculty who, by better understanding the journey of an academic researcher, can work in concert to reduce the barriers and increase the success of students’ research efforts. 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

ABSTRACTLettie Conrad reported on the findings of original research on academic user experience with serendipitous discovery in scholarly research. This research has been released as the fourth installment of a series about discoverability as part of the SAGE White Papers. This research was designed to examine how students and faculty seek content beyond the search box. The researchers being studied take advantage of unplanned or unexpected content discoveries such as selecting a link in an e-mail alert, following a trail of citations within an important paper, or making use of recommendations. The study found that researchers decide to follow recommendations, either machine generated or from an acquaintance, based on a combination of perception of relevance to the field of study, access to the recommended article, and trust in the provider. SAGE has used these findings to enhance its products to better showcase content to users and then help them to more readily make sense of it. 相似文献

A qualitative study of the impact of electronic journals on the information behavior of academic researchers at Catalan universities shows that academic researchers now read more, and more widely. However, their reading is becoming more superficial; they are compelled to improve their discrimination skills in order to decide what to read in more depth. The electronic accessibility of journals means that researchers now make fewer library visits. Web browsing and table of contents (TOC) e-mail alerts are replacing physical browsing, and searching is a very popular option for keeping up to date with developments. Internet search engines, especially Google and Google Scholar, are becoming important sources of information for researchers. However, they face problems in managing their personal scientific information. 相似文献

Search engine optimization, or the practice of designing a web site so that it rises to the top of the results page when users search for particular keywords or phrases, has become so prevalent on the modern web that it has a significant influence on Google search results. This article examines the techniques used by search engine optimization practitioners, the difference between “white hat” and “black hat” optimization tactics, and why it is important for library staff to understand these techniques and their impact on search engine results pages. It also looks at ways that library staff can help their users develop awareness of the factors that influence search results and how to better assess the quality and relevance of results listings. 相似文献

The new web-based academic communication platforms do not only enable researchers to better advertise their academic outputs, making them more visible than ever before, but they also provide a wide supply of metrics to help authors better understand the impact their work is making. This study has three objectives: a) to analyse the uptake of some of the most popular platforms (Google Scholar Citations, ResearcherID, ResearchGate, Mendeley and Twitter) by a specific scientific community (bibliometrics, scientometrics, informetrics, webometrics, and altmetrics); b) to compare the metrics available from each platform; and c) to determine the meaning of all these new metrics. To do this, the data available in these platforms about a sample of 811 authors (researchers in bibliometrics for whom a public profile Google Scholar Citations was found) were extracted. A total of 31 metrics were analysed. The results show that a high number of the analysed researchers only had a profile in Google Scholar Citations (159), or only in Google Scholar Citations and ResearchGate (142). Lastly, we find two kinds of metrics of online impact. First, metrics related to connectivity (followers), and second, all metrics associated to academic impact. This second group can further be divided into usage metrics (reads, views), and citation metrics. The results suggest that Google Scholar Citations is the source that provides more comprehensive citation-related data, whereas Twitter stands out in connectivity-related metrics. 相似文献

Google Scholar is a free service that provides a simple way to broadly search for scholarly works and to connect patrons with the resources libraries provide. The researchers in this study analyzed Google Scholar usage data from 2006 for three library tools at San Francisco State University: SFX link resolver, Web Access Management proxy server, and ILLiad interlibrary loan server. Overall, the data suggested that Google Scholar had become a very useful resource in the library and was a significant addition to the library's collection of research databases. SFX data revealed requests from Google Scholar grew ten-fold from 2006 to 2011, and that Google Scholar became the top-ranked SFX source for requests in 2011. Library patrons favored Google Scholar over San Francisco State University's federated search tool, MetaLib, and it has become an important source for interlibrary loan requests. Analysis of San Francisco State University usage data will assist other libraries in their decisions about the implementation of Google Scholar. 相似文献
