Available now: 2009 Journal Citation Reports Metrics

Journals Citation Reports (JCR) offers a systematic, objective means to critically evaluate the world's leading journals, with quantifiable, statistical information based on citation data. By compiling articles' cited references, JCR Web helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals.

All of the latest journal metrics are now available to you, including information for:

• More than 9,100 of the world's most highly cited, peer-reviewed journals
• 1,055 journals with their first published Journal Impact Factor
• Journals from over 2,200 publishers in 230 disciplines, from 78 countries
• Features that enhance your understanding of a journal's influence such as Five Year Impact Factors and Eigenfactor Metrics, Rank-in-Category Tables, Journal self-citations, and Impact Factor boxplots
  

The JCR can be accessed via the Web of Knowledge home page at: http://wok.mimas.ac.uk/ (off-campus access is via Raven password).

A quick reference card on how to use the JCR can be downloaded here: http://science.thomsonreuters.com/m/pdfs/mgr/qrc_jcr_april_09.pdf

New e-resource: JSTOR Plant Science

JSTOR Plant Science (http://plants.jstor.org/) is an online environment that brings together global plants content, tools, and people interested in plant science. It provides access to foundational content vital to plant science – plant type specimens, taxonomic structures, scientific literature, and related materials.

This new environment includes content from our Global Plants Initiative partners, bringing the amount of materials to 800,000 type specimens, paintings, drawings, correspondence, and supporting materials. By 2013, we expect to have over 2.2 million type specimens available, making JSTOR Plant Science the largest collection of its kind in the world. These materials are now truly global in scope representing over 160 partners in 47 countries on 5 continents. To learn more about this global network, see http://plants.jstor.org/page/plants/about/partners.jsp.

JSTOR Plant Science provides an interface with powerful functionality that supports research and teaching, including the ability to measure and record plant specimens, share observations and objects with colleagues and classmates, and investigate global plant biodiversity. To learn more about JSTOR Plant Science as a teaching tool, please contact training@jstor.org.

Aside from botanists and those dedicated to the plant sciences, JSTOR Plant Science is especially useful for Ecologists, Conservationists, Environmental scientists, Historians, Pharmacologists, Biologists, Geneticists, Agricultural Scientists, even Art Historians.

Access is available on and off campus (by Raven login) via the eresources@cambridge A-Z page at: http://www.lib.cam.ac.uk/electronicresources/and at: http://plants.jstor.org/
