and the text says "Data was supplied by the following members of OASPA as number of CC-BY articles per year since implementation of the license by that publisher:" Which means, obviously: Regardless of when they became members of OASPA. And implicitly, then, the growth of membership cannot influence this curve (Should there be a new member next year and they repeat the exercise, they would get a completely new curve which would lie entirely above the this current one, from the year *that* publisher started using CC-BY, not the year the publisher joined OASPA) best, Hans > > David > > > > On 11 Mar 2013, at 20:57, Heather Morrison wrote: > >> OASPA has posted a picture of a chart of CC-BY growth on their blog: >> http://oaspa.org/growth-in-use-of-the-cc-by-license-2/ >> >> The chart by itself is difficult to interpret.
