To evaluate the work of scholars objectively, funding agencies and tenure committees may attempt to quantify both its quality and impact. Quantifying scholarly work is fraught with danger, but the current emphasis on assessment in academe suggests that such measures can only become more important. There are a number of descriptive statistics associated with scholarly productivity. These fall broadly into two categories: those that describe individual researchers and those that describe journals.
Note the "Cited by" value beneath the citation. Such numbers may be added together, or perhaps averaged over a period of years, to provide an informal assessment of scholarly productivity. Better yet, use Google Scholar Citations to keep a running list of your publications and their "cited by" numbers.
Library Search-Ithaca College Library
One can conduct a library search, either the basic or advance search for the author(s) or by the title of an article (tip: put the article title in " "). Clicking on the upward facing arrow will give articles that cite this article. Clicking on the downward facing arrow will give articles that the cited article listed in the reference list. Make sure you are signed in with your Netpass username and password (upper right hand corner of library page) before searching.
Cited Reference Searching Guide: You might also look at this guide for additional resources to help track down if research is cited by other scholars.
The h-index, created by Jorge E. Hirsh of the University of California, San Diego, is described by its creator as follows:
A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np - h) papers have no more than h citations each.1
In other words, if I have an h-index of 5, that means that my five most-cited papers each have been cited five or more times. This can be visualized by a graph, on which each point represents a paper. The scholar's papers are ranked along the x-axis by decreasing number of citing papers, while the actual number of citing papers is shown by the point's position along the y-axis. The grey line represents the equality of paper rank and number of cited articles. The h-index is equal to the number of points above the grey line.
The value of h will depend on the database used to calculate it. 2 Thomson Reuter's Web of Science and Elsevier's Scopus (neither is available at IC) offer automated tools for calculating this value. In November of 2011, Google Scholar Citations became generally available. This will calculate h based on the Google Scholar database. There is also a Google Scholar H-Index Calculator for Google Chrome
Google Scholar Metrics includes lists of top-ranked journals by h index in a variety of subject areas.
Comparisons of h are only valid within a discipline, since standards of productivity vary widely between fields. Researchers in the life sciences, for instance, will generally have higher h values than those in physics.
A large number of modifications to the h-index have been proposed, many attempting to correct for factors such as length of career and co-authorship.
The Publish or Perish website also provides a way to calculate h-index based on Google Scholar reports. Note that each website is likely to give a different result because it indexes, and calculates based on, different sources.
Researchers at the National Institutes of Health have developed a method to quantify the influence of a research article by making novel use of its co-citation network to field-normalize the number of citations it has received. The beta version of iCite, can be used to calculate the Relative Citation Ratios of articles listed in PubMed.
Rightly or wrongly, the quality of a paper is sometimes judged by the reputation of the journal in which it is published. Various metrics have been devised to describe the importance of a journal.
The Impact Factor (IF) is a proprietary measure calculated annually by Thomson Reuters. This figure is based on how often papers published in a given journal in the preceding two years are cited during the current year. This number is divided by the number of "citable items" published by that journal during the preceding two years to arrive at the IF. Weaknesses of this metric include sensitivity to inflation caused by extensive self-citation within a journal and by single, highly-cited articles. For more information about the IF, see the essays of Dr. Eugene Garfield, founder of ISI. Determining a journal's IF requires access to Thomson Reuters Journal Citation Reports, not available at IC Library.
One can look at Researchify for the Impact Score of various journals. The impact score (IS), also denoted as Journal impact score (JIS), of an academic journal is a measure of the yearly average number of citations to recent articles published in that journal. It is based on Scopus data.
The eigenfactor is a more recent, and freely-available metric, devised at the University of Washington by Jevin West and Carl Bergstrom. Where the IF counts all citations to a given article as being equal, the eigenfactor weights citations based on the impact of the citing journal. Its creators assert that it can be viewed as "a rough estimate of how often a journal will be used by scholars." Eigenfactor values are freely available at eigenfactor.org.
The SCImago Journal Rank indicator (SJR) is another open-source metric. It uses an algorithm similar to Google's PageRank. Currently, this metric is only available for those journals covered in Elsevier's Scopus database. Values may be found at scimagojr.com.

Journal Acceptance Rate
The method of calculating acceptance rates varies among journals. Some journals use all manuscripts received as a base for computing this rate. Other journals allow the editor to choose which papers are sent to reviewers and calculate the acceptance rate on those that are reviewed that is less than the total manuscripts received. Also, many editors do not maintain accurate records on this data and provide only a rough estimate. Furthermore, the number of people associated with a particular area of specialization influences the acceptance rate. If only a few people write papers in an area, it tends to increase the journal's acceptance rate. Some journals will include the acceptance rate in the “information for authors” area of the print journal or on the home pages for the journal.
Selected sources for locating journal acceptance rates:
MLA International Bibliography, Choose Advanced Search, then Directory of Periodicals. You can then look up the periodical you are interested in.
American Psychological Association (APA) Journal Statistics and Operations Data -These PDFs provide information about manuscript rejection rates, circulation data, publication lag time, and other journal statistics
Association for the Advancement of Computers in Education (AACE) -submission review policy, acceptance rate and indices.
Cabell's Scholarly Analytics (The Ithaca College library does not subscribe to this, though individual academic departments/schools at IC may). Here is a recent article regarding it's use which may be of interest however. One useful thing that Cabell's does however is to publish a list of journals that are known as “Journalytics” in place of the formally known “whitelist” and “Predatory Reports” in place of formerly known “blacklist” journals. There is also, Beall's List of of Potential Predatory Journals and Publishers.
