If you want to stay abreast of new trends and developments in your profession, you may wish to read current issues of some of the leading journals in your field. You may even be looking for places to publish your own research. There are several ways to identify top journals in your field of study.
The UCA Library provides access to Journal Citation Reports (JCR), a database that compiles data for evaluating and comparing scholarly journals. JCR can assess a journal’s standing in scholarly literature through evaluation of citation data, and calculation of impact and influence metrics. Citation data is drawn from over 11,000 scholarly and technical journals from more than 3,300 publishers in over 80 countries. The JCR Science Edition contains data about more than 8,000 journals in science and technology. The JCR Social Sciences Edition contains data about more than 2,600 journals in the social sciences. JCR can tell you the most frequently cited journals, the highest impact journals, and the largest journals in a field.
Many of the most respected scholarly journals can be identified through a metric known as Impact Factor. Impact Factor is the average number of times articles from a journal published in the past two years have been cited in the selected JCR year. The Impact Factor is calculated by dividing the number of citations in the JCR year by the total number of articles published in the two previous years. An Impact Factor of 1.0 means that, on average, the articles published one or two year ago have been cited one time. A journal with a high Impact Factor has published articles that are cited more frequently, in comparison with other lower-impact journals. Of course, you may wish to consider self-citation rates as part of your journal evaluation. A self-citation is a reference to an article from the same journal, and a common practice in scholarly publishing.
However, Impact Factors are not set in stone, and are not the only metric for evaluating worthy journals. Impact Factor can fluctuate if a journal publishes more or fewer articles from year to year, or if the journal title changes. The Eigenfactor® Score measures the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers the source of these citations, so that highly cited journals will influence the network more than lesser cited journals. The Immediacy Index is the average number of times an article is cited in the year it is published. This metric may be especially useful when comparing journals specializing in cutting-edge research.
If you want to narrow your search, the Web of Science database can help you identify the most frequently cited articles on a specific topic. Web of Science covers over 12,000 of the highest impact journals worldwide, including open access journals. You can search by topic and identify the most cited articles on a subject. You can also search by publication name to find the most cited articles within a specific journal. Please note: the UCA Library does not have full text access to every article indexed in Web of Science, but some full text access is available.
