This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

International Collaboration accounts for the articles that have been produced by researchers from several countries. The chart shows the ratio of a journals documents signed by researchers from more than one country; that is including more than one country address.

YearInternational Collaboration

Not every article in a journal is considered primary research and therefore citable, this chart shows the ratio of a journals articles including substantial research (research articles, conference papers and reviews) in three year windows vs. those documents other than research articles, reviews and conference papers.
