Elsevier announced the adoption of two journal metrics, SNIP and SJR, for its Scopus database of abstracts and scholarly journal articles. SNIP, developed by the Centre for Science and Technology Studies, allows direct comparison of the frequency of citation between journals in different fields and other citation-based analyses. The second metric-SJR, or SCImago Journal Rank-was developed by the SCImago Research Group and serves to measure the scientific prestige of specific scholarly sources, weighted based on citations from other journals.
The inclusion of the two metrics will allow users of Scopus to better categorize and sort journal information and develop their own journal ranking systems. The metrics will be updated twice a year and are available to Scopus subscribers through the service's main site.
In related news, Elsevier announced that the Committee on Institutional Cooperation-a consortium that includes such institutions as Michigan State University, Pennsylvania State University, Purdue University, and the University of Iowa-agreed to purchase the complete ScienceDirect ebook collections from 2008, 2009, and 2010. The purchase will grant access to the full collection to all member institutions of the CIC, both remotely and on-site. Also included are search discovery tools such as the NextBio ontology-based semantic search tool.
Elsevier also launched its Pageburst interactive digital learning platform, powered by Elsevier's health science information content. Pageburst is designed to be a more efficient and student-friendly learning platform than traditional ebooks and includes features such as integrated multimedia, text-to-speech, social networking tools, and instructor grade books. Designed specifically for the needs of health and nursing students, Pageburst gives students access to course materials and references whether in or out of the classroom.
