Bibliometric profile of top-cited single-author articles in the Science Citation Index Expanded

In this study, we identified and analyzed characteristics of top-cited single-author articles published in the Science Citation Index Expanded from 1991 to 2010. A top-cited single-author article was defined as an article that had been cited at least 1000 times from the time of its publication to 2012. Results showed that 1760 top-cited single-author articles were published in 539 journals listed in 130 Web of Science categories between 1901 and 2010. The top productive journal was Science and the most productive category was multidisciplinary physics. Most of the articles were not published in high-impact journals. Harvard University led all other institutions in publishing top-cited single-author articles. Nobel Prize winners contributed 7.0% of articles. In total, 72 Nobel Prize winners published 124 single-author articles. Single-authored papers published in different periods exhibited different patterns of citation trends. However, top-cited articles consistently showed repetitive peaks regardless of the time period of publication. “Theory (or theories)” was the most frequently appeared title word of all time. Leading title words varied at different time periods, and only five title words, method(s), protein(s), structure(s), molecular, and quantum consistently remained in the top 20 in different time periods.

学科文献资源需求挖掘与保障分析——以河池学院应用化学学科为例

提出基于引文分析和数据挖掘的学科文献资源需求挖掘与保障分析方法,通过对河池学院应用化学学科进行实证分析,发现该学科的需求呈现资源类型、语种单一以及前沿性不强等特征,图书馆数字资源与实体资源馆藏对学科的保障互补性不强、重复建设多,对不同类型的文献需求保障不平衡,进而给出调整该学科资源建设的现实策略.     

A Quantitative Analysis of Research Output of Jawaharlal Nehru University,New Delhi,India

This study provides an overview of the research output of Jawaharlal Nehru University, New Delhi, India, in terms of number of publications contributed by faculty members and researchers. The study analyzes bibliometric indicators of published research of Jawaharlal Nehru University as indexed in the Web of Science. There were 5,007 research publications from Jawaharlal Nehru University in the four decades from 1971–2010 (70s; 80s; 90s; and 2000s). The study noted encouraging trends in collaborative research work with multiple-authored research papers. International collaboration in research was also observed among the faculty members and researchers. English was the predominant language of communication. The social scientists and humanists of Jawaharlal Nehru University publish books which are not indexed in the Web of Science. Similarly, research work published in regional languages or published in national level journals are seldom included in the Web of Science. It suggests that research needs to be done by collecting data from the Indian Citation Index and books published by the researchers in order to get an accurate and consolidated picture of the research output of the university.

Reaching Out to International Students: A Focus-Group Approach to Developing Web Resources and Services

Librarians at the State University of New York at Buffalo implemented the Resources for International Students Web guide to support library outreach to a multicultural and multilingual audience. A focus group helped librarians to understand the needs of new international students and tailor Web resources accordingly. In addition to creating awareness of international student cultural challenges, this article presents focus-group guidelines to assist in the planning process of library services and resources.     

The Feeling of ‘Silverland’

This is a discussion of the group of journalists working in and around Virginia City during the 1860s and 1870s, when the area became the world centre of the silver mining industry. The so-called Sagebrush writers reported on mining prospects for readerships locally and internationally, as well as writing anecdotes and stories about the life of the highly transient local communities generated by the search for silver. Theirs is writing characterised both by caution in responding to the mining industry and by an aggressive humour in depicting the local life of a cosmopolitan instant city. These newspaper writers have been considered in the local context of the Nevadan frontier. Here, I discuss their engagement with a complex and internationally networked industry, and also their address to the collectivities of the local population.
