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

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

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!

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

Want to know more?• Wikipedia is a good source – try

In the real world• Science Citation Index is now part of Web of Science,

which includes Social Science Citation Index and Arts and Humanities Citation Index

• 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.
