 In which section can we find more about peer review?
Shifting from ink on paper to digital text suddenly allows us to make perfect copies of our work. Shifting from isolated computers to a globe-spanning network of connected computers suddenly allows us to share perfect copies of our work with a worldwide audience at essentially no cost. I mean a group of authors defined by their topics, genres, purposes, incentives, and institutional circumstances, not by their wealth. If authors like that exist, at least they should take advantage of the access revolution. In any case, we can be more specific about which access barriers OA removes. These purposes include reading and searching, but also redistributing, translating, text mining, migrating to new media, long-term archiving, and innumerable new forms of research, analysis, and processing we haven’t yet imagined. While every kind of OA removes price barriers, there are many different permission barriers we could remove if we wanted to. Note that all three legs of the BBB definition go beyond removing price barriers to removing permission barriers, or beyond gratis OA to libre OA. But at the same time, all three allow at least one limit on user freedom: an obligation to attribute the work to the author. If there are complexities, they lie in the transition from where we are now to a world in which OA is the default for new research.
