The proliferation of open access journals has provided authors of scholarly works a choice in how their works are published and archived.  In doing so, open access journals have become competition for the mainstream so-called “toll access” journals.  Some of these traditional journals have therefore realized the potential of offering authors and institutions their own open options and thus formed hybrid “open access” journals.  This article will examine in detail exactly what a hybrid OA journal is and whether or not it qualifies as truly offering an “open” option for authors.  It will also determine the reasons that traditional journals have gone hybrid and it will take a look at how successful they are.  Lastly the article will explore the impact that hybrid journals have on the open movement to determine whether they support or undermine it.
