Research Questions
Does the research impact of OA articlesdiffer across the fields in sciences, social sciences, and arts and humanities?
If it does, do OA articles in hard, urban and convergent fields receive more citations (hence higher research impact) than those in soft, rural, and divergent ones?

Conclusion
Citation characteristics vary among disciplinesCitation behavior differs from self-archiving behaviorOA articles in hard, urban and convergent fields do not necessarily have higher research impactOA articles in Biology, Economics and Anthropology received more citations

Further Research
A more representative study with a larger sample size needs to be carried outThe relationship between research impact and self-archiving behavior should be investigated
