TL;DR: A size-independent indicator of journals’ scientific prestige, the SCImago Journal Rank (SJR) indicator, is proposed that ranks scholarly journals based on citation weighting schemes and eigenvector centrality and is designed for use with complex and heterogeneous citation networks such as Scopus.

TL;DR: In this article, a new size-independent indicator of scientific journal prestige, the SJR2 indicator, is pro- posed, which takes into account not only the prestige of the citing scientific journal but also its closeness to the cited journal using the cosine of the angle between the vec- tors of the two journals' cocitation profiles.

TL;DR: The SJR2 indicator was distributed more equalized than the JIF by Subject Area and almost as equalized as the SNIP, and better than both at the lower level of Specific Subject Areas, and the incorporation of the cosine increased the values of the flows of prestige between thematically close journals.

TL;DR: Using the Scopus dataset (1996–2007) a grand matrix of aggregated journal-journal citations was constructed, which can be compared in terms of the network structures with the matrix contained in the Journal Citation Reports of the Institute of Scientific Information (ISI).

TL;DR: Two journal metrics recently endorsed by Elsevier's Scopus are introduced: SCImago Journal Rank (SJR) and Source Normalized Impact per Paper (SNIP).
