Bibliometrics

This guide provides an overview of bibliometrics (the statistical analysis of books, articles, or other publications) and Dartmouth's resources on the topic.

Metrics for Journals

Journal Impact Factor
Measures the frequency with which an average article from a particular journal is cited in a given year

CiteScore
(# of citations to articles published in Journal X in previous 4 years) / (# of articles published in Journal X in previous 4 years)
Includes articles, reviews, conference papers, book chapters, and data papers, but does NOT include editorials, errata, letters, notes, or short surveys

Eigenfactor
Measures the impact of journals on the scientific community with weight given to the size of the journal

Google Scholar Metrics
Compares journals by their h5-index (he largest number h such that h articles published in the past 5 years have at least h citations each)

SCImago Journal & Country Rank (SJR)
Uses information in the Scopus database to comparatively rank both journals and countries

Source Normalized Impact per Paper (SNIP)
Measures the impact of a paper within a particular subject field over the past 3 years

Metrics for Articles

Citation Counts
How many total citations has the article received?

Field Weighted Citation Impact (FWCI)
Ratio of actual number of citations received to expected number of citations based on the average of the subject field.

A FWCI of:

  • Exactly 1 means that the output performs just as expected for the global average.
  • More than 1 means that the output is more cited than expected according to the global average. For example, 1.48 means 48% more cited than expected.
  • Less than 1 means that the output is cited less than expected according to the global average.

Metrics for Authors

Citation Counts
How many total citations have the author's publications received?

H-Index
The maximum value h such that the given author has published at least h papers that have been cited at least h times
