These databases allow you to set up citation alerts:
Web of Science is the most widely used database for tracking citations.
It includes several tools which researchers use for determining the impact of their work:
This guide will show how to use the Web of Science to:
Bibliometrics serves as a way to produce and analyze data regarding publication impact and citation frequency. It can be used to answer questions about how journals and articles might rank in importance and influence.
The Becker Medical Library has developed an extensive resource guide for measuring the impact of publication which should supplement the information presented here. An additional website outines their model for assesing and improving impact.
A further useful introdiction is the following:
WHITE PAPER Using Bibliometrics in Evaluating Research by David A. Pendlebury, Research Department, Thomson Reuters, Philadelphia, PA USA
From the paper:
Ten Rules in Citation Analysis
1. Consider whether available data can address the question.
2. Choose publication types, field definitions, and years of data.
3. Decide on whole or fractional counting.
4. Judge whether data require editing to remove “artifacts”.
5. Compare like with like.
6. Use relative measures, not just absolute counts.
7. Obtain multiple measures.
8. Recognize the skewed nature of citation data.
9. Confirm that the data collected are relevant to the question.
10. Ask whether the results are reasonable.
And, above all, present the results openly and honestly.
Google has created Google Scholar Citations, a tool that will allow an author to show their citation metrics over time, including an h-index score and total citation count as determined by Google Scholar's database. "After you identify your articles, we collect citations to them, graph these citations over time, and compute your citation metrics..." A public profile page can also be created.
Keep in mind that google includes and gives equal weight to citations in such non-traditional media such as websites, powerpoints, word docs and blogs.
