This paper examined the roles of academic libraries in open access journal publishing in terms of monetary supports for publication. As a result, many academic libraries have participated in the cooperative programs such as COPE(Compact for Open-Access Publishing Equity) and <TEX>$SCOAP^3$</TEX>(The Sponsoring Consortium for Open Access Publishing in Particle Physics) for authors to publish their research in open access journals. Also, 13 academic libraries in North America have set up the campus-based open access author funds individually. Most of academic libraries in participating COPE did not fund for research that have been published in the hybrid open access journals. In addition to publication funds, academic libraries provided authors or scholarly societies with such services as copyright negotiation, technological supports of the publication process, and the dissemination of open access publications.
