Not all Open Access is created equal. To move beyond the seemingly simple question of “Is it Open Access?” PLOS, SPARC and OASPA have collaborated to develop a resource called “HowOpenIsIt?” This resource identifies the core components of open access (OA) and how they are implemented across the spectrum between "Open Access" and "Closed Access". We recognize there are philosophical disagreements regarding OA and this resource will not resolve those differences. 
 
We are seeking input on the accuracy and completeness of how OA is defined in this guide. Download the open review draft and provide feedback below in the comment form on SPARC's website. In its final form, this guide will provide an easily understandable, comprehensive, and quantifiable resource to help authors make informed decisions on where to publish based on publisher policies.

With this guide we aim to provide greater clarity regarding its definition and components. All suggestions will be considered and a final version will be released during Open Access Week (October 22 -28, 2012). The comment period will close on Monday, October 8, at 5:00pm (EST).
