3. Citation indexing
Invented in 1961 by Eugene Garfield at the Institute for Scientific Information (ISI)
Scientific abstracting/indexing services began in nineteenth century, recording author/title/publisher/source etc for articles and indexing them
Garfield added details of all references quoted in the article and indexed them too, publishing results as Science Citation Index (SCI) – originally only in printed form
Allowed for many new ways of linking articles

4. Exciting new ways For an article you’ve read:
Find earlier articles that one was based on
Find later articles which quoted it
Find related articles which quote some of the same references as this one
So you can trace the progress of ideas backwards, sideways and, uniquely, forwards in time

5. And
You can identify which journals publish most highly-cited articles – the notorious ‘impact factor’
Publishing your work in high-impact journals is important in getting funding!
Bibliometric analysis to be used in next research assessment exercise (REF)

6. also
Discover who is citing your research, or that of a colleague, or noted authority
Identify sources of information that competitors are consulting for their research
Construct an objective history of a field of study, significant invention, or discovery

7. Originally Using the paper Science Citation Index was hard work
Now, the electronic version is much quicker to use
But can be complex and confusing – important to understand what it does and doesn’t do
Caveat emptor!
SCI now has competitors, but all work slightly differently – e.g. Scopus, Google Scholar
The basic concept of linking documents which cite each other, and ranking them according to the frequency with which they do so, underpins search engines like Google

Wikipedia is a good source – try

9. In the real world
Science Citation Index is part of Web of Science, which includes Social Science Citation Index and Arts and Humanities Citation Index, and also now Conference Proceedings
Web of Science is a product offered on the platform Web of Knowledge (WoK), alongside other products including Journal Citation Reports which gives journal impact factors.
Direct access available on Oxford network; outside Oxford log in using SSO

61. Journal Citation Reports (JCR)
For Sciences and Social Sciences
This is a measure of the frequency with which the "average article" in a journal has been cited in a particular year. The impact factor will help you evaluate a journal's relative importance, especially when you compare it to others in the same field
From within a record you can click on Journal Citation Reports to view the impact factor of the journal
Or you can view and compare impact factors of all journals within your subject area

69. Sample Search in Scopus

75. Citation searching in Google Scholar
References include ‘cited by’ data based on articles known to Google Scholar

Still useful for tracking research

80. Citation searching Is very useful Should be used with care
Excellent for keeping up with new articles and people
Bibliometrics is an art not a science!
