6. H-index
A researcher 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.
H-index also applies to
journals
7. Journal Metrics/Impact
Tools used to check high impact journals in your research fields
Journal Citation Reports (JCR) – impact factor, 5 year impact
factor, immediacy index, article influence
Scimago Journal & Country Rank – SJR, country rankings
Google Scholar metrics – h5-index and h5-median
9. SJR:
Scimago Journal and Country Rank
What it does
• The SCImago Journal & Country Rank is a
portal that includes the journals and country
scientific indicators developed from the
information contained in the Scopus®
database (Elsevier B.V.). These indicators can
be used to assess and analyze scientific
domains.
Metrics
• Total Cites
• H Index
• SJR indcator
Limitations • Elsevier
Demonstration • Covers 19,000 journals
10. SJR bibliometrics
• SJR - measures the journals impact, influence
or prestige. It expresses the average number
of weighted citations received in the selected
year by the documents published in the
journal in the three previous years
• H-Index – the journal’s number of articles (h)
which have received at least h citations over
the whole period
12. ISI Journal Citation Reports
What they do
• Allows comparison and evaluation of journals
using citation data drawn from scholarly and
technical journals. Contains data from journals
in science, technology and social sciences.
Metrics
• Total Cites
• Impact factors
• Immediacy Index
• Eigenfactor score
Limitations
• Little use in arts
• Ineffective for new journals
Demonstration • Access from Library Databases webpage
13. Bibliometrics in JCR
• Total cites - the total number of times that each journal has
been cited by all journals included in the database within
the current JCR year.
• Impact Factor - identifies the frequency with which an
average article from a journal is cited in a particular year.
• Immediacy Index - measures how frequently the average
article from a journal is cited within the same year as
publication. This number is useful for evaluating journals
that publish cutting-edge research.
• Eigenfactor Metrics are based on the JCR cited journal data
and consider not just the counts of citations a journal
receives but also the significance of the journals as a whole
to measure citation influence in the scholarly literature.
15. Measuring author impact
• Same metrics are used to measure author
impact
• Number of citations and number of
publications
16. Google Scholar profile
• My citations – set up a profile to automatically retrieve
publications and citations (last 5 years)
• Includes citation counts, H-Index & i10 index
• Future publications and citations automatically updated
21. An example of how different the numbers are

Scopus 135 1719 29
Web of Science 54 320 16
Publish or Perish 953 34991 84
22. Benefits of Open Access
• Satisfies the requirements of research funders
requiring open access publication, such as
Marsden, UK Research Councils, the NIH,
Wellcome Trust and many othersBigger impact
- potential for greatly increased dissemination
and citation advantage
• More equitable impact – access is for all, not
just those who can afford journal
subscriptions.
23. OA Citation Advantage
Total number of studies so far 70
Studies that found a citation advantage 46
Studies that found no citation
advantage
17
Studies that were inconclusive, found
non-significant data or measured other
things than citation advantage for
articles
7

24. Open Access Myths
• OA articles are not copyrighted
• OA articles are not peer reviewed
• OA articles are free
• OA articles have a lower impact factor
• OA will harm scholarly societies
25. Directory of Open Access Journals
• 8,858 / 1,987,356. Number of peer-reviewed
OA journals and articles listed in the Directory
of Open Access Journals (DOAJ).
• 338 (or 3.8%). Number journals with the DOAJ
Seal of Approval in the DOAJ.
• 6. Number of titles added daily to the DOAJ in
the quarterly period between December 31,
2015 and March 31, 2016

• Traditional bibliometrics measure the impact
of articles in academic journals. Technology
and OA have made other types of metrics
possible e.g. Impactstory
• Altmetrics, cybermetrics or webometrics
include impact in social media – Twitter,
Mendeley, blogs, Facebook etc

41. How to maximize research impact 1
Co-publish (especially internationally).
Target high impact journals in your subject field
Set up a Google Scholar profile and encourage your co-author/s to do so
Put your publications in UC Repository indexed by Google Scholar and
Scopus
Consider Open Access (OA) Journals (see Directory of Open Access
Journals).
Use social bookmarking tools to promote your publications, e.g.
CiteULike, Mendeley
42. Submit your peer reviewed manuscript to repositories – Subject (arXiv, RePeC)
and Institutional repositories.
Set up an ORCID ID so that all your publications contribute to your research
profile
If the journal you publish is not indexed by Scopus, ask the journal editors to
contact Scopus to see if it can be included.
Choose straight-forward title keywords when writing papers so that they appear
on top of the search results
Join in professional bodies & professional networks, e.g. LinkedIn

44. • According to the most recent survey (2015),
roughly one in three authors said that it was
“very important” to them that the journals in
which they publish make articles freely
available, far fewer than said Impact Factor or
the ability to publish for free were very
important; interestingly, that number is down
from 55% in the 2003 survey (according to
Figure 23 in the report on the 2009 survey).
Editor's Notes
Dame Janet Finch – how to expand access to research publications and to accelerate the progress toward a fully OA environment
The prestige of a journal is usually measured by the number of times papers have been cited and downloaded from this journal
Now we move to the subject of measuring the impact of the output of individuals. The most widely accepted measure of an individual’s research impact is the h-index. The h-index was proposed by physicist Jorge Hirsch in 2005 and although it’s been criticized in some areas, it has generally been positively received.
Pro: Advantage of h-index is that it simultaneously measures both the quantity (number of papers) and the quality (impact or number of citations). An academic can’t have a high h-index without publishing a substantial numbers or papers nor without those papers being cited by others.
This is the algorithm for calculating the h-index
Basically your h index is calculated at the point where a number of publications coincide with the same no. of citations. It’s much more easily explained with by using a few examples to illustrate how the h-index works and some of the criticisms that have been levelled against it. We will address some of these points as we look at the tools available to calculate H-index and other measures of impact
Con: doesn’t account for number or order of authors; fields vary in number of references cited; bounded by number of publications. May produce inconsistent results, eg “if two researchers with a different h-index co-author a paper together, it may lead to a reversal of their position in an h-index based ranking”.
Ignores citations over and above what is needed to obtain a certain h-index. Less useful to measure academic achievement of junior academics

Gold – This means publishing in a way that allows immediate access to everyone electronically and free of charge. Publishers can recoup their costs through a number of mechanisms, including through payments from authors called article processing charges (APCs), or through advertising, donations or other subsidies
Green - depositing the final peer-reviewed research output in an electronic archive called a repository. Repositories can be run by the researcher’s institution, but shared or subject repositories are also commonly used. Access to the research output can be granted either immediately or after an agreed embargo period.
