Traditional scholarly publishing involves commercial and society journals with editorial boards and peer review. New publishing models like open access, open archives, and author self-archiving have emerged due to electronic publishing advantages and rising journal costs. Open access involves free access to content while retaining traditional structures. Open archives allow free depositing of articles in repositories. Author self-archiving allows authors to publish their own research freely online. These new models shift costs from consumers to producers and provide quick publication but quality assurance and discoverability are concerns that need to be addressed for viability. A mix of models is predicted to continue with disadvantages regarding organization, discoverability, quality, and access.
