Journal Metrics
Journal Metrics
Journal metrics are used to identify key journals in a research
field. This identification may be most useful to authors who are
considering which journals to submit manuscripts to for future
publication.
The Impact Factor may be the most familiar metric in academia. Eugene
Garfield of Thomson Scientific first introduced this idea in the 1950s.
Impact Factor calculations are now available through Thomson’s Journal
Citation Reports (JCR) and the Elsevier product, Scopus. However, each
database tends to be biased in favor of including journals that are
published by that particular publisher.
Despite their merits, journal metrics can be misused particularly in
the evaluation of individual authors. Newer measures of impact are
decribed on the altmetrics tab and provide an alternate way to evaluate scholarly impact.

Conducting Literature Reviews
Scholars will often publish journal articles that assess and
evaluate the top ranked journals in their field. Conduct a search in a
large interdisciplinary database such as Proquest Social Sciences Premium Collection or EBSCO's Academic Search Premier using
keywords such as "top journals" or "highly ranked journals" and the
field. For example, you could search in Academic Search Premier using
the terms "top ranked journals" and "economics". You can also select a
narrower subject specific database such as EconLit. Alternatively search across a number of different databases for full-text articles using the Google Scholar search option.

Harvard Databases
- Journal Citation ReportsPublished
by Thomson Reuters, Journal Citation Reports is a resource for journal
evaluation, using citation data drawn from over 8,400 scholarly and
technical journals worldwide in the sciences and social sciences.
Coverage is both multidisciplinary and international, and incorporates
journals from over 3,000 publishers in 60 nations. 1999-present.
Publication coverage is uneven and tends to include a high number of
Thomson Reuters publications.
Free Web Sites
- Academic Journal GuideA
guide published by the Association of Business Schools, that evaluates
the quality of journals in which business and management academics
publish their research. Based on a combination of peer review, editorial
and expert evluations and citation metrics. Free registration required. - Publish or PerishPublish
or Perish is a free author and journal impact metrics software program
developed by Anne Wil Harzing that retrieves and analyzes citations to
articles and books. The software uses Google Scholar to obtain the raw
citations. Analyzes and presents article citation statistics for authors
and journal titles. The tool can be used to locate most cited articles
and books by searching in general citations field. - SCImago Journal & Country RankThe
SCImago Journal & Country Rank is a portal that includes the
journals and country scientific indicators developed from the
information contained in the Scopus® database (published by Elsevier).
These indicators can be used to assess and analyze scientific domains.
This indicator shows the visibility of the journals contained in the
Scopus® database from 1996.
Google Metrics
- Google Scholar MetricsBrowse
the top 100 publications in several languages, ordered by their
five-year h-index and h-median metrics. Also, search for publications by
their titles, and then compare the publications that are of interest to
you. Finally, if you wish to see which articles in a publication were
cited the most and who cited them, click on its h-index number to view
the articles as well as the citations underlying the metrics.
You
can also explore publications in research areas of interest to you. To
browse publications in a broad area of research, select one of the areas
in the left column.
Altmetrics/ Other Metrics
Article & Author Level Metrics
- Google Scholar CitationsYou
must register for a Google account to use this service using an academic
email account. Track citations to your publications. Check to see what
authors are citing to your publications. Graph your citations over time.
Authors of scholarly articles should check their Google Scholar page to
verify that your publications listings are accurate and comprehensive. - PLoS PublicationsPLoS
is a nonprofit organization founded in 2000 by biomedical scientists to
makes scientific and medical literature available to public. In 2003,
the publisher started an open access scientific and medical publishing
arm with high-quality journals including its flagship, peer reviewed
publication, PLos One. In March 2009, PLoS introduced article-level
metrics to provide a measure of merit for individual articles rather
than merely journal metrics. - Publish or PerishPublish
or Perish is a free author and journal impact metrics software program
developed by Anne Wil Harzing that retrieves and analyzes citations to
articles and books. The software uses Google Scholar to obtain the raw
citations. Analyzes and presents article citation statistics for authors
and journal titles. The tool can be used to locate most cited articles
and books by searching in general citations field.
- Web of ScienceA
multidisciplinary database, with searchable author abstracts, covering
the journal literature of the sciences, social sciences and arts.
Generate citation reports by author. Create citation maps for articles.
Defining Altmetrics
The terms "altmetrics"
(alternative metrics) and "article level metrics" have been used to
describe approaches to measure the impact of scholarship by using new
social media tools such as bookmarks, links, blog postings, inclusion in
citation management tools and tweets to gauge the importance of
scholarly output.
Proponents
of altmetrics believe that using altmetrics will help measure the
impact of an article in a more comperhensive and objective way thaa was
done perviously with journal metrics databases like Journal Citation
Reports. However, there are limits to this approach and caution should
be used to not rely on any one particular measure in evaluting the
importance of scholarship.

Altmetrics
- Altmetrics, a manefestoWeb
site devoted to altmetrics. Started by group of librarians and
researchers who are active in promoting altmetrics as an alternative to
more traditional forms of tracking article impact. - Impact StoryImpactStory aggregates altmetrics measures from articles, datasets, blog posts, and more.
- Peer EvaluationPeer
Evaluation is a web site for giving open access to primary data,
working papers, articles, media and having the works reviewed and
discussed by your peers. Peer evaluation is a strong supporter of
qualified peer reviewing and considers their web site a valuable
supplement, inspiration and hub for peer reviewed journals and
publications. - ScholarometerScholarometer
is a browser extension designed for crowdsourcing scholarly data by
using Google Scholar citations to measure scholarly impact. You have to
install the extension in your browser (Chrome or Firefox).
