Who’s citing you? Citation tracking tools.
Angela Carritt & Juliet Ralph
In this session• Who has cited my papers?• Citation indexing in Web of Science, Scopus & Google
Scholar.• Find highly-cited papers or authors.• Create citation alerts. • Which journals should I publish in?
• Impact factors.

Why bother• Trace the progress of research backwards, forwards and
sideways
• Identify sources of information used by 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
Search example• 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 search for book review
• 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)
Scopus• 15,000 journals in• Science • Medicine• Social sciences
• “Cited by”• Citation tracker
Cited references in Google Scholar• References include ‘cited by’ data based on articles known
to Google Scholar• Entries ranked by number of cites• Not possible to sort, save sets or analyse• Still useful for tracking research
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,
WileyInterScience• Number of times it has been cited in that database. • Look for links such as “Cited by”, “Citing articles”
Related records• Find similar articles based on shared references.• Links now appear in databases such as• Web of Science• Databases on Ovid platform• PubMed• Google Scholar
Impact factors: Journal Citation Reports• Indices for comparing academic journals • Based on citation data from Web of Science• Covers
• > 5,900 journals in science and technology• > 1,700 journals in the social sciences
• Use with caution…• Results are skewed by many factors e.g. size of journal, type of
content, frequency/time of publication…• Journals which are not indexed by WOS disadvantaged• English language favoured…• Problems when journals change names• Results are not comparable across disciplines• …
JCR• Total cites = total number of citations to the journal for a year• Impact factors = how many times the average article was cited during the
year (calculated: number of citations in the year to articles published in the previous 2 or 5 years divided by total number of articles published in that period)
• Immediacy index – how quickly articles are cited (calculated: number of citations to articles published in the year divided by the total number of articles published in the year)
• Cited half-life – Number of years from the current year accounting for half of citations to the journal
• Eigenfactor metrics – use “Google style” algorithms to rank journals. Look at wider networks of citations rather than just “times cited” and take into account factors such as prestige of citing sources - http://well-formed.eigenfactor.org/

rankings• Mystified by metrics? Anxious about impact factors? Happy
with your h-index? The forthcoming Research Excellence Framework is likely to place increased emphasis on the use of these measures. This session covers how they work, how they are interpreted and how to make them work for you!Presenter: Roger Mills
