More information about journal pricing is available at
Ted Bergstrom's Journal Page. Also see our sibling EigenFactor.Org and our project on Big Deal Contracts. Here are some of our opinions. Here are summary statistics. Finally, here are explanations of the calculations for 2011, 2010 and 2009.
This website represents our best attempt to compute the price per article and price per citation. Currently we use the ISI data for citations 2005-9 and 2010 prices, which are the most recent data available to us. Not all journals report information the same way, and errors are possible. You can report errors by writing to us. The coloration (red for very low value, yellow for low value, and green for good value) is computed by comparing the composite price index to the median for non-profit journals in the same subject.
Be advised that price per citation, price per article and the composite index are not perfect measures of value. Neither of us are experts in most of the fields represented, and others may reasonably, or unreasonably, disagree with the value assessment. We have mapped a large set of journal categories into 17 areas. Here is the full mapping. Many journals that are published by large commercial publishers are owned by non-profit societies, who control the pricing. These publishers usually refuse to tell us which journals they own and which they publish for non-profits. We have determined the non-profit status of more than 100 such journals, but undoubtedly we have missed some. Please let us know about any that we have missed.
