WISER: Bibliometrics I Who’s citing you? Angela Carritt & Juliet Ralph angela. carritt@bodleian. ox. ac. uk juliet. ralph@bodleian. ox. ac. uk March 2011

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

{ } 2010 2009 2010 Later papers that cite “your” paper Papers that share one or more citation in common - related 2006 2008 1980 1870 2007 } Earlier papers referred to in “your” paper

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 Power. Point presentations in lectures", Computers & Education, vol. 41, no. 1, pp. 77. • Effectiveness of Power. Point 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)

Wo. S: 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 Wo. S 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 Wo. S • 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, Psyc. Info, BIOSIS Previews …and other life science databases on the Ovid platform JSTOR Full-text databases such as Science. Direct, 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 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 • Web of Science • Scopus
