Journal ranking alternatives to the journal impact factor
There are two new journal ranking tools freely available on the internet.
SCImago Journal & Country Rank — Data from Scopus (13,200 journals)
Eigenfactor — Data from Thomson (8,000 journals)
The SJR indicator (from SCImago Journal & Country Rank) and the Eigenfactor take the ISI Impact Factor one step further. They incorporated a PageRank algorithm from Google to weight the citing journals. The ISI Impact Factor counts the number of cites to papers in a journal but does not distinguish if the citing paper is published in a prestigious journal or a not so highly ranked journal. The SJR indicator and the Eigenfactor take into account the ranking of the citing journal.
