In this post I show that there is no correlation between journals prices and Article Influence Score of journals.

In my last ‘About Archaeology Journal Publishing’ post I compared the Eigenfactor score of journals. The same people who created the Eigenfactor also create what they call the Journal Influence Score. Full details of how this score is calculated can be found here. The website describes a Journal Influence Score as:

Article Influence score measures the average influence, per article, of the papers in a journal. As such, it is comparable to Thomson Scientific’s widely-used Impact Factor. Article Influence scores are normalized so that the mean article in the entire Thomson Journal Citation Reports (JCR) database has an article influence of 1.00.

In 2006, the top journal by Article Influence score is Annual Reviews of Immunology, with an article influence of 27.454. This means that the average article in that journal has twenty seven times the influence of the mean journal in the JCR.

As before, I took the Article Influence Score of archaeology journals (a list can be found here, same list as the Thomson Impact Factor) and compared it against the prices of those journals, the results can be seen in the graphs below:

Article Influnce Score Vs. Price of Journals

Article Influnce Score Vs. Price of Journals

Article Influnce Score Vs. Price per Page of Archaeology Journals

Article Influnce Score Vs. Price per Page of Archaeology Journals

As with the other scores I have covered there is no positive correlation between prices and the quality of journals. In fact, the high negative R2 number indicates that as price does up the quality goes down.
