What is Bibliometrics?
- The branch of library science concerned with the application of mathematical and statistical analysis to bibliography; the statistical analysis of books, articles, or other publications. ("bibliometrics, n.". OED Online. December 2011. Oxford University Press.)
- In other words…data about publications, or citation frequency.
- Scientometrics is the branch of information science concerned with the application of bibliometrics to the study of the spread of scientific ideas; the bibliometric analysis of science. ("scientometrics, n.". OED Online. December 2011. Oxford University Press.)
Why is this important?
Citation Analysis was originally conceived as a way to correct for subjective perception. Instead of just making an educated guess about the most prestigious journal in a field, citation analysis provides a mathematical measure of how many articles from the journal have been cited over a specific time frame, adding a measure of objectivity.
As a supplement to the peer review process, citation analysis can also be used to measure how an individual's publications have affected his or her field. This information is often used in making tenure decisions
Questions citation analysis can help answer:
A student asks you "What are the best journals in the field of Anthropology?"
A professor asks you "Who is citing my articles? How many times have I been cited?"
A student asks you "How do I know this article is important?"
A professor asks you "Which journal should I publish in?"
- Journal collections
- Research Funding
- Expertise status in the field
- Finding others in the field/subject area (using citation searching)
New research is being done to define 'altmetrics' that also define a researcher's impact. The method of communication can vary but is outside of the traditional journal article.
