A journal impact factor measures the importance of a journal by calculating the times its articles are cited.
The best source for journal rankings is Journal Citation Reports, a database that can be accessed through Web of Science or Web of Knowledge. Mabee Library does not subscribe to Journal Citation Reports. There are, however, alternative sources for this information. Links are provided below to some of these alternatives.
Eigenfactor.org
"Eigenfactor® scores and Article Influence® scores rank journals much as Google ranks websites. Scholarly references join journals together in a vast network of citations. Our algorithms use the structure of the entire network (instead of purely local citation information) to evaluate the importance of each journal. Eigenfactor.org not only ranks scholarly journals in the natural and social sciences, but also lists newsprint, PhD theses, popular magazines and more."
Google Scholar Metrics
"Google Scholar Metrics provide an easy way for authors to quickly gauge the visibility and influence of recent articles in scholarly publications. While most researchers are familiar with the well-established journals in their field, that is often not the case with newer publications or publications in related fields - there're simply too many of them to keep track of! Scholar Metrics summarize recent citations to many publications, to help authors as they consider where to publish their new research."
Harzing.com - Journal Quality List
"The Journal Quality List is a collation of journal rankings from a variety of sources. It is published primarily to assist academics to target papers at journals of an appropriate standard."
Journal M3trics
"The academic community has long been demanding more transparency, choice and accuracy in journal assessment. Currently, the majority of academic output is evaluated based on a single ranking of journal impact. Bibliometricians have been exploring new methods to provide deeper insight. Within the field of journal evaluation, two of the most exciting are Source Normalized Impact per Paper (SNIP) and SCImago Journal Rank (SJR), those values are provided here free of charge."
