Bibliometrics and Indexing

Bibliometrics

GAIA encourages applying due care in interpreting the following bibliometric indicators. GAIA has signed the San Francisco Declaration on Research Assessment (DORA), pointing to flaws in the calculation and use of the Journal Impact Factor. GAIA would also like to point to the Leiden Manifesto for Research Metrics, which states ten principles to better guide research evaluation.

...GAIA's Journal Impact Factor (JIF) is 1.87 (2019). The JIF measures the total citation frequency. Basis of the calculation are all journals listed in the Web of Science; GAIA is listed both in the Science Citation Index Expanded (SCIE) and in the Social Science Citation Index (SSCI).
...The 5-year Journal Impact Factor is 1.75 (2019). 
...The SJR SCImago Journal Ranking – which provides a quantitative and qualitative measure of the journal's impact – is 0.453 (2019).
...SNIP (Source Normalized Impact per Paper) is 0.559 (2019). SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field, using Scopus data. 
...The Eigenfactor – which rates the total importance of a scientific journal according to the number of incoming citations – is 0.00062 (2019). 
...GAIA's Document H-Index is 27 (2019) – the measure expresses the number of GAIA articles (h) that have received at least h citations. It quantifies both GAIA's scientific productivity and scientific impact. 
...The CiteScore – the average citations per document in a 2 year period – is 2.2 (2019).
