Across all fields, Open Access articles in Swedish repository have a higher citation rate than non-OA articles.

Due to differences in citation practices amongst scientific disciplines, existing research on a possible open access citation advantage remains limited. A new study seeks to overcome these limitations by investigating whether there is a possible OA citation advantage across all fields. Lars Kullman presents his findings on cross-field citation comparisons between OA and non-OA articles from the Chalmers University of Technology self-archive repository. The results indicate an advantage. The OA articles studied in this paper have a 22% higher field normalized citation rate than the non-OA articles.
