Bibliometrics (such as impact factors and journal rankings) are an attempt to quantify importance, prestige, and value of scholarly publishing.
There are many kinds of metrics that measure different things, as well as many different inputs and algorithms that lead to those metrics.
Journal Citation Reports (JCR) provides ranking for journals in the areas of science, technology, and social sciences. They also calculate journal Impact Factor, the average number of times articles from the journal published in the past two years have been cited in the JCR year. This measure is a frequently used indicator as to the significance and influence of the journal in its field. Please note that the Library does not currently subscribe to the JCR. Please check with your local public or academic library to access them.
Opinions vary widely as to what constitutes a "good" impact factor. Click here for a chart which provides some context, in terms of how many journals achieve the various ranking levels. Also, please keep in mind that consideration of a good impact factor may vary by discipline. A number that is considered low in one field might be considered quite high in another field. Therefore, the Library recommends consulting with your Dissertation Chair to find out if they require a minimum impact factor for your concept paper or dissertation references.
While the Library does not subscribe to the JCR there are some databases which provide impact factor for their published journals. Follow the instructions in the below box to find impact factor in the Library and online.

Scimago Journal and Country Rank (SJR) is an open-access database containing citation information on more than 17,000 scholarly and professional journals based on content from Elsevier's Scopus collection.
SJR is a prestige metric based on the idea that ‘all citations are not created equal’. With SJR, the subject field, quality and reputation of the journal has a direct effect on the value of a citation. SJR differs from other bibliometric measures in that it:
Follow the instructions below to find SJR using the Scimago Journal and Country Rank website.
Content: Citations and articles in multi-disciplines not found through a NavigatorSearch.
Purpose: Used to conduct topic searches as well as find additional resources that have cited a specific resource (citation network).
Follow the instructions below to find a journal's ranking using the Library’s Web of Knowledge database.
The quartile is given as either Q1, Q2, Q3, or Q4 where Q1 indicates that the journal is in the top 25% of its subject category while Q4 indicates it is in the bottom 25% of the journals in that category.
Google Scholar Metrics provides a way for researchers to easily assess article visibility and influence. Google Scholar Metrics has compiled a list of the top 100 Publications in Several Languages. The publications in this list are ranked by their 5 year h-index and h-median metrics. By clicking on the number under the h-index, you can view a list of that publication's most cited articles as well as who cited them.
Example: Click on the h-index number to view the most cited articles within the publication, Nature.
This will identify a list of those articles in addition to the subcategory under which Google Scholar Metrics has labeled Nature.
Google Scholar has also compiled lists of the top publications within the following fields. Each category maintains supplemental subcategories as well. Please note that these are only English-language lists at the moment.

The Microsoft Academic Search Engine offers Journal Rankings based on the dynamic eigencentrality measurement. The Journal Analytics feature automatically extracts information from publications and their metadata. Journals are indexed in a variety of disciplines, and are more likely to be included if they are easily discoverable on the web.
Microsoft Academic's Journal Analytics allows users to filter by the following measurements:
Users can also filter by topic, year, and keyword search.
To access the Journal Analytics from the Microsoft Academic main page, click on 'Journals' located to the right of the screen. This will redirect you to the Journal Analytics page.
There have been numerous criticisms regarding the use of impact factor to measure the quality of a journal. Therefore, alternate bibliometric measures have evolved to address shortcomings, and to provide alternate perspectives on journal or article significance. These alternate measures further described below include: Eigenfactor Score, Article Influence Score, SCImago Journal and Country Rank (SJR), H-Index, and SNIP (Source Normalized Impact per Publication).For further details about journal impact criticism, see the scholarly article below.
Eigenfactor.org is an academic research project sponsored by the Bergstrom Lab in the Department of Biology at the University of Washington with the purpose of ranking and mapping scientific knowledge. Eigenfactor Scores and Article Influence Scores are calculated similarly to the methodology used by Google to rank webpages. Scholarly references link journals together in a large network of citations and allows for a comparison across disciplines.
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. Eigenfactor scores are intended to give a measure of how likely a journal is to be used, and are thought to reflect how frequently an average researcher would access content from that journal.
The Article Influence Score calculates measures the relative importance of the journal on a per-article basis.
Follow the steps below to search a database of Eigenfactor and Article Influence scores from 1997 to 2015.
Developed by J.E. Hirsch, the h-index is a number intended to represent both the productivity and the impact of a particular scientist or scholar, or a group of scientists or scholars (such as a departmental or research group). The h-index is calculated by counting the number of publications for which the scientist has been cited by other authors at least that same number of times. In comparison with the ISI Impact factor, the h index corrects for highly cited papers not found in highly cited journals. This presents an unbiased way of comparing people within a discipline, especially in the sciences.
Web of Knowledge
Content: Citations and articles in multi-disciplines not found through a NavigatorSearch.
Purpose: Used to conduct topic searches as well as find additional resources that have cited a specific resource (citation network).
Follow the instructions below to find h index using the Library’s Web of Knowledge database.
Scimago Journal & Country Rank
Follow the instructions below to find h index using the Scimago Journal & Country Rank website.
Google Scholar
Google Scholar has adapted the h-index method of impact. h5-index is the h-index for articles published in the last 5 complete years. It is the largest number h such that h articles published in 2013-2017 have at least h citations each. You can browse the top 100 publications in several languages, ordered by their five-year h-index and h-median metrics.
Follow the instructions below to find h index using Google Scholar Metrics.
CWTS Journal Indicators provides free access to bibliometric indicators on scientific journals. The indicators have been calculated by Leiden University’s Centre for Science and Technology Studies (CWTS) based on the Scopus bibliographic database produced by Elsevier. Indicators are available for over 20,000 journals indexed in the Scopus database.
A key indicator offered by CWTS Journal Indicators is the SNIP indicator, where SNIP stands for source normalized impact per paper. This indicator measures the average citation impact of the publications of a journal. Unlike the well-known journal impact factor, SNIP corrects for differences in citation practices between scientific fields, thereby allowing for more accurate between-field comparisons of citation impact. CWTS Journal Indicators also provides stability intervals that indicate the reliability of the SNIP value of a journal. More information on the indicators offered by CWTS Journal Indicators is available on their Methodology page.
Follow the instructions below to locate SNIP using the CWTS Journal Indicators website.
