2. Overview of Session What is citation indexing Why is it useful How to use it on Web of Science Citation searching on other products Setting up alerts and organising your references with RefWorks or EndNote

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

8. Want to know more? Wikipedia is a good source – try http://en.wikipedia.org/wiki/Citation_index http://en.wikipedia.org/wiki/Citation_index

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

10. 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

11. Other services offering citation searching - SCOPUS Sciences and Social Sciences Results include journal articles and web pages Each reference to a paper shows the number of times an article has been cited

12. Citation searching in Google Scholar References include ‘cited by’ data based on articles known to Google Scholar Entries ranked by number of cites Not possible to save sets or analyse Still useful for tracking research

13. 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!
