Citation Advantage of Open Access Legal Scholarship …

Citation Advantage of Open Access Legal Scholarship :

“To date, there have been no studies focusing exclusively on the impact of open access on legal scholarship. We examine open access articles from three journals at the University of Georgia School of Law and confirm that legal scholarship freely available via open access improves an article’s research impact. Open access legal scholarship – which today appears to account for almost half of the output of law faculties – can expect to receive 50% more citations than non-open access writings of similar age from the same venue.”

Did Online Access to Journals Change the Economics Literature? :

Does online access boost citations? The answer has implications for issues ranging from the value of a citation to the sustainability of open-access journals. Using panel data on citations to economics and business journals, we show that the enormous effects found in previous studies were an artifact of their failure to control for article quality, disappearing once we add fixed effects as controls. The absence of an aggregate effect masks heterogeneity across platforms: JSTOR boosts citations around 10%; ScienceDirect has no effect. We examine other sources of heterogeneity including whether JSTOR benefits “long-tail” or “superstar” articles more.”

Fractional counting of citations in research evaluation: An option for cross- and interdisciplinary assessments :

“In the case of the scientometric evaluation of multi- or interdisciplinary units one risks to compare apples with oranges: each paper has to assessed in comparison to an appropriate reference set. We suggest that the set of citing papers first can be considered as the relevant representation of the field of impact. In order to normalize for differences in citation behavior among fields, citations can be fractionally counted proportionately to the length of the reference lists in the citing papers. This new method enables us to compare among units with different disciplinary affiliations at the paper level and also to assess the statistical significance of differences among sets. Twenty-seven departments of the Tsinghua University in Beijing are thus compared. Among them, the Department of Chinese Language and Linguistics is upgraded from the 19th to the second position in the ranking. The overall impact of 19 of the 27 departments is not significantly different at the 5% level when thus normalized for different citation potentials”.

How and why scholars cite on Twitter

Scholars are increasingly using the microblogging service Twitter as a communication platform. Since citing is a central practice of scholarly communication, we investigated whether and how scholars cite on Twitter.

We conducted interviews and harvested 46,515 tweets from a sample of 28 scholars and found that they do cite on Twitter, though often indirectly. Twitter citations are part of a fast-moving conversation that participants believe reflects scholarly impact. Twitter citation metrics could augment traditional citation analysis, supporting a “scientometrics 2.0”.
