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!
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
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

Analyzing results
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
