ONLINE through UC CDL license: Impact Factors and Journal Rankings
Journal Citation Reports (JCR): As of late 2008, UC campuses have access to JCR as part of a CDL consortial license.
Thomson Reuters notes that “Journal Citation Reports® offers a systematic, objective means to critically evaluate the world’s leading journals, with quantifiable, statistical information based on citation data. By compiling articles and cited references, JCR Web helps to measure research influence and impact of research journals and shows the relationship between citing and cited journals.” JCR is available in Science and Social Sciences editions.
NOTA BENE: Definition of terms, details on how the metrics are calculated, and information on the validity, manipulation, and misuse of Impact Factors are provided at the following Wikipedia entry:
GETTING STARTED: The JCR link at the top takes you to the default setting of reviewing SCIENCE journals by broad subject categories. After clicking SUBMIT, choose your preferred category (you may need to review several in interdisciplinary fields) and SUBMIT. Note that the sort order is alphabetic by journal title. For the most common rankings arrangement, change the “Sorted by” in the top left to IMPACT FACTOR and click on SORT AGAIN.
CAVEAT: Review journals typically rank very highly using this method. It is not unusual for the top ten in a subject category for this type of ranking to have several review journals listed.
HELP AVAILABLE: All BioAg library classes on literature searching now include a section on using this new resource. Sign up for a BioAg class at:
