ISI Journal Citation Reports (JCR) offers a means to statistically compare and evaluate some of the world's leading journals.
- Delivers quantifiable statistical information based on citation data.
- Provides a variety of impact and influence metrics, including the Journal Impact Factor and Eigenfactor®
- Includes rank-in-category tables, journal self-citations, and Impact Factor boxplots
JCR provides comparison data for how journals rank among other titles in a subject category and by citation value and impact factor. One can also retrieve historical trend data for several years to see the direction of the impact. However a specific article can trigger a measurement that is a one-time spike.
Go to ISI Journal Citation Reports.
You can see that it offers a choice of two collections - the JCR Science Edition (which includes medicine) and the JCR Social Sciences Edition, and that you will need to specify a year.
The database can be viewed by journal groupings (of subject, publisher, or country of origin); searched for a specific journal; or accessed in its entirety.
Searching the Science Edition, year 2011; and selecting to view journals by Subject Category, provides an opportunity to choose from a long list of categories. Selecting "Computer Science - Artificial Intelligence" and clicking on Submit provides 111 results, sorted alphabetically by journal title.
The list can be resorted by the following options.
Sorting by Impact Factor, for example, can give a better idea of the most important journals in the field.
Clicking on a journal's name gives more specific information about that journal, including the option to view various graphs.
Click on the Impact Factor Trend Graph.
Information such as this can help you see how a journal's impact factor has changed over time. Comparisons with other journals might indicate rising or decreasing influence. However, due to differences in databases and algorithms, more than one type of ranking index should be consulted in the overall analysis of a journal's significance in a field.
By studying journal impact metrics, such as those presented in this database, scholarly researchers and academic organizations can make better informed decisions about the importance of the journals they purchase and publish in.
Caveat: JCR metrics are limited to articles indexed in Web of Science. For best results, multiple sources and methods should be used in identifying the most significant journals and articles in a research area.
