How Open Is It?
In 2002, the Budapest Open Access Initiative (BOAI) articulated the basic tenets of Open Access (OA) for the first time. Since then, thousands of journals have adopted policies that embrace some or all of the OA core components related to: readership; reuse; copyright; posting; and machine readability.
PLOS, SPARC and OASPA have collaborated to create a guide that identifies the core components of OA and how they are implemented across the spectrum between “Open Access” and “Closed Access”. The guide provides an easily understandable, comprehensive, and quantifiable resource to help authors make informed decisions on where to publish based on publisher policies. In addition, funders and other organizations will have a resource that indicates criteria for what level of OA is required for their policies and mandates. This OA guide is aimed toward a wide audience of researchers, authors, and policy-makers.
