 What is the main premise of OA?
OA makes work more useful in both ways, by making it available to more people who can put it to use, and by freeing those people to use and reuse it. OA was defined in three influential public statements: the Budapest Open Access Initiative (February 2002), the Bethesda Statement on Open Access Publishing (June 2003), and the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities (October 2003). The purpose of OA is to remove barriers to all legitimate scholarly uses for scholarly literature, but there’s no legitimate scholarly purpose in suppressing attribution to the texts we use. The basic idea of OA is simple: Make research literature available online without price barriers and without most permission barriers.
