Impact Factor and Other Ways of Assessing the Research Value of a Journal: Eigenfactor Ranks

Various ways to assess the research value of a journal.

What is this measure?

The Eigenfactor score is a rating of the total importance of a journal, newspapers, popular journals, etc. Journals are rated according to the number of incoming citations, with citations from highly-ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly-ranked journals

Eigenfactor includes a feature to factor in journal cost, and generate cost effectiveness measures for titles.
