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

What if my journals aren’t in WoS?

Master List of ISI journals - 12,000 journals which form the basis of Web of Science and Journal Citation Reports (JCR).

Try Scopus• Huge bibliographic database:• 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Scopus (especially non-English language), plus conferences, books, dissertations/theses, unpublished items such as Powerpoint shows etc…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 a feature in many databases:

• Medline, Embase, PsycInfo, BIOSIS Previews• …and other databases on the Ovid site• 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”

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 many of those extra ones were from low-impact journals or conference proceedings.

Coverage compared•Web of Science – 12,000 core journals, but weak on conferences.

•Scopus – 18,000 international journals (some overlap with WoS) & conferences, but weak coverage pre-1996.

•Google Scholar – good for conference proceedings and international, non-English language journals, but weak coverage pre-1990.
