A comprehensive and unique resource that allows you to evaluate and compare journals using citation data drawn from thousands of scholarly and technical journals. JCR can show you:
* the most frequently cited journals in a field
* the highest impact journals in a field
* the largest journals in a field
Journal Impact Factor Definition: The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to measure the importance or rank of a journal by calculating the times its articles are cited.
How is the Impact Factor Calculated? The calculation is based on a 2-year period and involves dividing the number of times articles were cited by the number of articles that are citable.
* Use to determine if a particular journal is peer-reviewed or refereed
*Peer-review/refereeing is the process in which the science and research contained within journal articles is examined by experts for accuracy and for quality, before the articles are accepted for publication
* In Ulrich's, peer-reviewed journals are identified by little referee sweater symbols
* For journals not listed in Ulrich's, look up the journals' editorial policies and instructions to authors (on their websites), to find out if the journals are peer-reviewed
