New Analysis on the impact of Open Access availability on citations finds out, that Open access increases cites to the top-ranked journals but reduces cites to lower-ranked journals.
Two Economists, Mark McCabe (University of Michigan School of Information) and Christopher Snyder (Dartmouth College), have published a new study of the impact of open access on citation rates for science journal content. McCabe and Snyder found that open access increases citation rates for high-quality content, while reducing citations to lower-quality content. In their paper, “The Rich Get Richer and the Poor Get Poorer: The Effect of Open Access on Cites to Science Journals Across the Quality Spectrum,” McCabe and Snyder construct a model to explain their findings, which was based on an analysis of 100 journals in ecology, botany, and general science. The authors document what they call a “superstar effect,” in which the benefits of open access (namely, increased citations) accrue to higher quality content and journals, while lower-tier content does not receive such benefits.

Citation analysis in RePEc is very popular among Economists worldwide. So far it is mainly based on citations in reference lists of Journal Articles and Working Papers. But as Social Media are more and more used not only for academic networking, but also for scholarly discussions, an extended impact analysis is up for discussion.
In his latest Blog Entry RePEc member Christian Zimmermann proposes some extensions to the existing RePEc rankings, e.g. the inclusion of Wikipedia or Economics Blogs. In order to get a better understanding of the Community View, Zimmermann started an Online Voting. The results are open for everyone and show so far, that there’s a split within Economists, with one part being open for the inclusion of Social Media for citation analysis, while others are very sceptical.
This shows, that there’s definitely some change going on the scholarly publication landscape in Economics, but so far Social Media are still controversial, when it comes to quality assessment of research papers. Nevertheless there are tools like Altmetrics, who show, that impact analysis goes beyond journal impact factors. And even large research organisations like the Leibniz Association in Germany with it’s research network “Science 2.o” have started to analyse how Social Media are affecting scholarly communication.

New edition of webometrics ranking compares repositories worldwide and by region according to several categories.
The “Ranking Web of Repositories” is a service provided by the Spanish Reseseach Organization CSIC. Besides comparing repositories it also ranks Universities, Business Schools and Hospitals. The repository ranking is published every 6 months, now in it’s 12th edition.
Compared to earlier rankings EconStor has climbed several places and now ranks at number 52 worldwide, with the TOP positions held by SSRN, ArXiv and the NASA Astrophysics Data System. Looking at fulltext content only (category “rich files”), EconStor fares even better, being now number 15 worldwide and number 7 in Europe.
