This document discusses open access publishing models as an opportunity or threat to scholarly publishers. It defines open access as providing free access to research articles online with different business models than traditional print journals. Key drivers of open access include ubiquitous internet access, increasing research volumes, and rising journal prices. Open access journals have article processing fees paid by authors' grants and shift costs from readers to authors. Strategic issues for publishers include threats to revenue but also opportunities to rethink business models to incorporate open access options. Over time, open access is expected to moderate prices while benefiting readers and libraries.
