Open access (OA) publishing, whereby authors, their institutions, or their granting bodies pay or provide a repository through which peer-reviewed work is available online for free, is championed as a model to increase the number of citations per paper and disseminate results widely, especially to researchers in developing countries. We compared the number of citations of OA and non-OA papers in six journals and four books published since 2000 to test whether OA increases number of citations overall and increases citations made by authors in developing countries. After controlling for type of paper (e.g., review or research paper), length of paper, authors’ citation profiles, number of authors per paper, and whether the author or the publisher released the paper in OA, OA had no statistically significant influence on the overall number of citations per journal paper. Journal papers were cited more frequently if the authors had published highly cited papers previously, were members of large teams of authors, or published relatively long papers, but papers were not cited more frequently if they were published in an OA source. Nevertheless, author-archived OA book chapters accrued up to eight times more citations than chapters in the same book that were not available through OA, perhaps because there is no online abstracting service for book chapters. There was also little evidence that journal papers or book chapters published in OA received more citations from authors in developing countries relative to those journal papers or book chapters not published in OA. For scholarly publications in conservation biology, only book chapters had an OA citation advantage, and OA did not increase the number of citations papers or chapters received from authors in developing countries.

Prior research has suggested that providing free and discounted access to the scientific literature to researchers in low-income countries increases article production and citation. Using traditional bibliometric indicators for institutions in sub-Saharan Africa, we analyze whether institutional access to TEEAL (a digital collection of journal articles in agriculture and allied subjects) increases: (i) article production; (ii) reference length; and (iii) number of citations to journals included in the TEEAL collection. Our analysis is based on nearly 20,000 articles - containing half a million references - published between 1988 and 2009 at 70 institutions in 11 African countries. We report that access to TEEAL does not appear to result in higher article production, although it does lead to longer reference lists (an additional 2.6 references per paper) and a greater frequency of citations to TEEAL journals (an additional 0.4 references per paper), compared to non-subscribing institutions. We discuss how traditional bibliometric indicators may not provide a full picture of the effectiveness of free and discounted literature programs. [ABSTRACT FROM AUTHOR]

We examine the bibliometric profile ofTropical Medicine and International Healthusing the subjects of the articles published and the geographical distribution of the authors. The most common subject areas of papers published during 1996–2003 are highlighted, and the most cited papers indicated. [ABSTRACT FROM AUTHOR]
