This research analyzes retracted biomedical literature in PubMed to determine if open access and fee for access works differ in terms of the practice or effectiveness of retraction. Citation and content analysis were applied to articles grouped by accessibility (libre, gratis, and fee-for access) for various bibliometric attributes. Open access literature does not differ from fee-for-access literature in terms of impact factor, detection of error, or change in post-retraction citation rates. Literature found in the PubMed Central Open Access subset provides detailed information about the nature of the anomaly more often than less accessible works. Open access literature appears to be of similar reliability and integrity as the population of biomedical literature in general, with the added value of being more forthcoming about the nature of errors, when such are identified.


Dr. Peterson is an Assistant Professor at the School of Library and Information Sciences at North Carolina Central University in Durham, NC. He holds bachelor’s degrees in Biochemistry (BS), Chemistry (BA), and Spanish (BA) from New Mexico State University, and an MS in Biotechnology from the University of Texas at San Antonio. He earned his Doctorate in Information Science from the University of Missouri in 2006.  He joined North Carolina Central University School of Library and
Information Sciences in 2007.

Dr. Peterson’s research interests pertain to the intersection of health sciences and biomedical literature and the Information Society. Health literacy and open access to scientific and health information can improve lives by reducing health information disparities. It is important to understand how to make high-quality information accessible to those who can benefit most
from it. One aspect of his research focuses on scholarly communication and the use of health information: He studies the self-correcting attributes of science.  He is the author of the upcoming (2013) article “Characteristics of retracted open access biomedical literature: a bibliographic analysis” in the Journal of the American Society of Information Science and Technology, the top-ranked publication in the field of Information Science. Current research examines the impact of anomalous literature on human subjects. His greater goal is to promote access to free, high quality information to under-served populations.
