Impact Factors & Journal Citation Reports

August 17th, 2009 by Ruth Gustafson

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:

You may also request an appointment with a BioAg librarian subject specialist by e-mailing or by calling the BioAg Reference Office, Monday-Friday, 9am-5pm at                   (530)752-6196

Environmental Abstracts Database Now Available at UC Davis

August 13th, 2009 by Kathy Stroud

CSA’s Environmental Sciences and Pollution Management (ESPM) database, a top scientific journal index for researchers in all areas of the environmental sciences, has just added the Environmental Abstracts database. Now, when you search ESPM (online access provided by UC Davis Library), you automatically search Environmental Abstracts as well. You may also choose to search Environmental Abstracts separately.

Beginning in 1975, Environment Abstracts indexes articles on all aspects of the impact of people and technology on the environment and the effectiveness of remedial policies and technologies. In 1994 the database expanded coverage to energy-related issues. Major areas of coverage now include:

• Air quality
• Bacteriology
• Ecology
• Energy resources
• Hazardous waste
• Industrial hygiene
• Pollution: land, air, water, noise, solid waste, radioactive
• Risk assessment
• Toxicology & toxic emissions
• Waste management
• Water resource issues

More than 950 scientific journals published in the U.S. and abroad are covered as well as conference proceedings, reports, and government publications. Significant monographs, government studies and newsletters are also selectively indexed. Visit the Environment Abstracts information page for more information. As with ESPM, you may use the embedded sfx button to acquire articles of interest that your searches have discovered. Many of these articles are available electronically through Library subscriptions and you can access them from your own desktop.

Email for assistance with searching Environmental Abstracts or any of the other environmental databases the library provides access to. We will be happy to schedule a one-on-one session with you to enhance your searching abilities. We also develop customized instruction for groups.
