Impact factor or index
The IF of a journal measures the number of times that the articles published a this journal during the two years preceding a given year.
- Journal Citation Reports (JCR)
Accessible through ISI Web of Knowledge. There are 2 editions: JCR Social Science Edition, JCR Science Edition. It does not cover the humanities.
It includes other complementary indices: H-index, immediacy index, quartile, Eigen factor, article influence.
JCR Tool A new tool developed by the Spanish Science and Technology Foundation (FECYT), this makes it possible to consult the information about the impact factor, as well as other metrics that can be obtained from the Journal Citation Report (JCR).
- SCImago Journal & Country Rank (SJR)
Developed by the SCImago group using data from Scopus. This includes a series of academic indicators for journals and countries.
- SJR: the subject, quality, and reputation of the publication have a direct impact on the value of the citation
- Scopus Journal Analyzer: desde Scopus.
It has two metrical indices: SJR and SNIP (Source-Normalized Impact per Paper): this measures the contextual impact of citations weighting them in accordance with the total number of citations in a given subject area. Useful for research areas with a lower probability of citations
- INRECH : Spanish Journals Impact Factor in Humanities (2004-2008)
- INRECS: Spanish Journals Impact Factor in Social Sciences (1996-2011)
- INRECJ: Spanish Journals Impact Factor in Legal Science (1996-2011)
- Potential Impact Factor of Spanish Medical Journals
Prepared by the López Piñero History of Science and Documentation Institute. Its main aim is to identify the national and international IF of Spanish biomedical journals.
- Citations in Economics (CitEC)
Analysis of citations of documents included in Repec. It includes a ranking with the IF of journals and working documents.
- Google Scholar Metrics (GSM)
This provides an impact index for academic journals, measured according on their h-index, making it possible to consult the hundred most cited journals in the world by language of publication. Spanish journals are ordered according to the h-index calculated between the years 2007-2011. The most cited articles from each particular journal can also be seen. Journals published in English allow consultations by areas and disciplines.
- Journal Scholar Metrics: Arts, Humanities & Social Sciences
Bibliometric tool that seeks to measure the performance of Art, Humanities, and Social Science journals by counting the number of bibliographic citations their articles have received according to Google Scholar.
GSM mainly covers scientific journals (~95% of the sources). The rest of the sources are conference proceedings (mostly from Computer Science and Engineering), and collections in repositories (i.e. arXiv, SSRN). Only journals, conference proceedings, or repository collections which have published at least 100 papers in the last five complete years and received at least one citation are included in this product.
There are two bibliometric indicators computed for every journal: the H5-index (h-index computed from the citations to documents published in the last five years) and the H5-median (median of the citation counts in the documents that contribute to the H5-index).
- Índice H de las revistas científicas españolas según Google Scholar Metrics (2011-2015)
A ranking carried out by the EC3 Group to overcome the limitations of GSM. It organizes the Spanish journals that appear in GSM by academic field and discipline and orders them by the h-index. Its aim is to test Google Scholar Metrics' breadth of coverage of Spanish academic journals.
