The Impact Factor (IF) of a scientific journal has been a key parameter for many years for the evaluation of the academic output of research groups and scientists and, in many cases, of the relative quality of individual papers.
A recent paper in FASEB Journal describes the analysis of a new ranking of journals, in comparison with the standard IF. The SCImago Journal Ranking (SJR) is based in the Scopus database (covering more than 13.000 journals); it is freely available and incorporates in the calculations a weighting factor accounting for the relative importance of the journals that are generating the respective citations. The authors found that the median absolute change in the ranking positions between IF and SJR was 29-32 for the top 100 journals.
This freely available resource can be a useful alternative tool for the researchers working in human genetics, in terms of the evaluation and consideration of publications in the area and to get an overview of the performance (number of publications, number of citations, number of citations per publication, H index, among others) of regions or countries in specific research subjects and years.
