This paper provides information on a research project undertaken at the University of Arkansas in Fayetteville to study publications by the campus researchers with an emphasis on the STEM (agricultural sciences, physical science, biological sciences, engineering and mathematics, etc.) disciplines at the macro level for a 3-year period. The overall objective of the study was to provide evidence-based data of periodical use to assist with collection decisions and to identify collection strengths at the university level. We used the Web of Knowledge database (Science Citation Index, Social Science Citation Index, and Arts and Humanities Citation Index) to identify the periodical literature in which our researchers published and those that they cite in their publications. We also determined the extent to which our researchers are publishing in and citing periodicals from the Elsevier, Wiley, and IEEE journal packages. A methodology for extracting citations from Web of Knowledge into an Excel spreadsheet is also provided. 相似文献

An initial discussion of Scopus and its development was published in volume 49, number 3 of The Serials Librarian. This article updates readers on the continuing progress in its development, including the integration of research performance measurement tools, Web and patent references, and other additions that have been made from the fall of 2005 through September 2007. Additionally, this article details the strides made regarding content covered within Scopus, including the addition of seven million archive records in early 2007 and the agreement with ProQuest to link through to its arts and humanities selection through Scopus. 相似文献

SUMMARY This session presented several case studies of libraries facing challenges following a decision to move materials to an off-site storage facility. The presenters described the entire process of moving materials to an off-site location: from planning and selecting materials to organizing the collection off-site, with an emphasis on the unique problems created by serials. All three presenters shared strategies and decision-making methods with the audience. 相似文献

A utility patent application may result in two citable documents: a published patent application (PPA) and a patent if the application is granted. Most analytic works consider only citations to the patent and ignore those to the PPA. This study gathers more than 270,000 U.S. utility patents granted in 2014 and their PPAs, and compares their citation counts up to 2018. Statistics show that citations to patents, on the average, account for less than 50 % of those to the patents and their PPAs combined together, indicating a significant underestimation to the value or impact of the patents. The degree of depreciation is worse when the time gaps between patents and their PPAs are longer, as the PPAs not only have accumulated citations for a longer period, but also individually, concurrently, and continuously receive citations after the patent is granted. This study further applies Main Path Analysis to a conventional citation network involving only citations to the patents and another network augmented with those to the PPAs, using empirical data from United States Patent and Trademark Office (USPTO) Cancer Moonshot Patent Data. The main path derived from the augmented network is almost entirely different from that of the conventional network. 相似文献
