The basic engine allows you to filter your search by journal name, the year, and an extensive list of subject categories. The advanced search offers the same options available under the basic engine but adds the ability to search by JCR subject category, publisher, and also to select whether to display results according to the article’s influence, name, or its EigenFactor. Finally, the cost-effectiveness engine allows you to filter your search to get the most bang for your buck when choosing which journal to purchase. Scholarly references join journals together in a vast network of citations. Eigenfactor uses the structure of the entire network, instead of purely local citation information, to evaluate the importance of each journal.
