Bibliometrics (and altmetrics) are ways to measure and compare research publications, authors, departments, and institutions. These metrics allow one to 

  • Find the best journals in a field
  • Find how often an article is cited
  • Determine highly cited articles and authors in a field

Bibliometrics affect

  • Researchers and authors
  • Library journal collections
  • Research funding
  • Tenure and promotion
  • Expertise status in the field
  • Finding others in a field/subject area
  • Eigenfactor

    The Eigenfactor score of a journal is an estimate of the percentage of time that library users spend with that journal. An Eigenfactor is based on the number of cited references, with citations from highly ranked journals weighted to make a larger contribution than those from poorly ranked journals.

  • h-index

    The h-index can measure an author's relative research impact, as opposed to a simple citation count. The h-index is based on the set of the author's most cited publications and the number of cited references those publications have received. The h-index is an alternative to the journal impact factor metric.

  • Journal impact factor

    An impact factor is a measure of the frequency that the "average article" published in a scholarly journal has been cited in a two or five year period. It is often used to measure or describe the importance of a particular journal in an academic discipline. Authors can use impact factors to evaluate journals to decide which to publish in.
