In this session
• Citation tracking - what it is and why its important
• Finding out who’s citing you using:
•
Web of Science
•
Scopus
•
Google Scholar.
• Creating citation alerts
Next session
• WISER Bibliometrics II: The Black Art of Citation Ranking more on measuring research impact

Why bother
• Trace the progress of research backwards, forwards and
sideways
• Identify research papers in your field / stay ahead of
competitors
• Assess the impact of your research – grants / jobs
Web of Science
•
•
•
•
Science Citation Index Expanded (SCI)--1945-present
Social Sciences Citation Index (SSCI)--1956-present
Arts & Humanities Citation Index (A&HCI)--1975-present
Conference Proceedings Citation Index- Science (CPCI-S)-1990-present
• Coverage: thousands of journals, conference papers,
review papers, notes of meetings, letters, book reviews, art
exhibits, poetry…but not books (yet!)
Search example
• Bartsch, R.A. & Cobern, K.M. 2003, "Effectiveness of PowerPoint
presentations in lectures", Computers & Education, vol. 41, no. 1,
pp. 77.
• Effectiveness of PowerPoint presentations in lectures
• Bartsch, RA & Cobern, KM
• Source: COMPUTERS & EDUCATION Volume:
41 Issue: 1 Pages: 77-86 Published: AUG 2003
• Cited references
• Times cited
General v Cited Reference
• General
• quick and easy but may be incomplete
• can also search for book reviews
• Cited Reference search
• Thorough – picks up variant citations
• Includes books (cited by papers on WOS)
• Includes publications that pre date the
citation indexes (cited by WOS)
WoS: Book Citation Index
• Coming soon…second quarter of 2011
• Initially 25,000 book titles
•
Scholarly titles containing original research (not text
books etc)
•
back to 2005 for Sciences
•
back to 2003 for Social Sciences / Humanities
• Includes references, footnotes, bibliographies
Cited references in Scopus
•
•
•
•
•
•
Huge bibliographic database covering
18,000 scholarly journals & conference proceedings in
Science, Medicine, Social sciences & Humanities
www.scopus.com
“View references” displays the article’s bibliography.
“Citations” column indicates times the article was cited
•
by other articles in Scopus
•
since 1996.
Citations column
NB ‘since 1996’
Cited references in Google
Scholar
• References include ‘cited by’ data based on articles known
to Google Scholar
• Entries ranked by number of cites
• Picks up citations in journals not covered by WoS or
Scopus (especially non-English language), plus
conferences, books, dissertations/theses, unpublished
items such as Powerpoint shows etc…
• Not possible to sort, save sets or analyse
How did they compare?
• In October 2010:
• Web of Science
•
42 citing articles; 19 unique to WoS
• Scopus
•
45 citing articles; 10 unique to Scopus
• Google Scholar
•
117 citations; 79 unique
•
But beware of phantom citations
• 19 references in common across the 3 databases.
Other databases
• Citing articles are becoming a feature in many databases
•
•
•
•
•
Historical Abstracts
Medline, Embase, PsycInfo, BIOSIS Previews
…and other life science databases on the Ovid platform
JSTOR
Full-text databases such as ScienceDirect, Wiley Online
Library
• Number of times it has been cited in that database.
• Look for links such as “Cited by”, “Citing articles”
Citation Alerts in WoS

Quality or quantity?
• Meho, L. I.; Yang, K. (2007). "Impact of
Data Sources on Citation Counts and
Rankings of LIS Faculty: Web of
Science vs. Scopus and Google
Scholar".
• Journal of the American Society for
Information Science and Technology 58
(13): 2105–2125.
• doi:10.1002/asi.20677
Meho and Yang’s study
found that:
•Google Scholar identified more
citations than Web of Science and
Scopus combined
•but most of those extra ones were
from low-impact journals or
conference proceedings.
Coverage compared
• Web of Science - strong coverage of journal
publications, but poor coverage of high impact
conferences.
• Scopus - better coverage of conferences, but
poor coverage of publications prior to 1996.
• Google Scholar - best coverage of conferences
and most journals (though not all), but like
Scopus has limited coverage of pre-1990
publications.
Bibliometrics
•If you want to count or analyse your
citations or ‘impact’, the tools to use
are
