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non-historical documents in PMC have a CC BY licence, and so 76% of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.
