From: Richard Poynder <[log in to unmask]> Date: Mon, 23 Jan 2017 16:39:41 +0000 OA advocates maintain that the formative definition of open access agreed at the meeting that led to the Budapest Open Access Initiative means that only papers with a CC BY licence attached can be described as open access. And yet millions of papers in open repositories are not available with a CC BY licence. Take, for instance, PubMed Central, which currently has 4.2 million documents deposited in it. A recent search shows that only 24% of the non-historical documents in PMC have a CC BY licence, and so 76% of the content cannot be described as open access. The good news is that the CC BY percentage in PMC is growing over time. Nevertheless, that it has still only reached 24% a decade after the NIH Public Access policy came into effect suggests that the OA movement still has a way to go if it is to live up to the BOAI definition.
