Study confirms that Open Access increases citation impact


A new study conducted by scientists in Canada and the UK reveals that articles that are freely accessible in Open Access repositories are cited more frequently.  Professor Harnad and his colleagues at the University of Quebec in Canada and the University of Southampton in the UK examined the research article output of the four institutions with the longest-standing Open Access mandates: the School of Electronics and Computer Science at the University of Southampton in the UK, CERN (the European Organisation for Nuclear Research) in Switzerland, Queensland University of Technology in Australia, and Minho University in Portugal. The team compared the citation frequency of the publications from these institutions with comparable publications from institutions without an OA mandate. In some cases, authors from the latter institutions made their work openly accessible anyway. However, in most cases they did not. The study confirms the effect of Open Access on citation. OA articles were cited significantly more than non-OA articles, even when other variables were controlled.
