hi Eric,
Thank you for sharing your data.
It is a good point that measuring growth requires repeated collection of the
same measures at different points in time. That is why I developed Dramatic
Growth as a quarterly series over a decade ago.
It is a fact that Open access archives have grown
Heather,
In the absence of strong evidence, it is difficult to speak of a dramatic
growth. The specific challenge of measuring OA availability is that in order to
measure growth you need to measure at different points in time with the same
measure or to be able to re-calibrate your measures
Interesting question and direction. This raises at least two different
questions for me:
1. Is access via for-pay discovery tools and knowledge bases a goal for
open access? I am concerned that the most liberal open licenses, allowing
downstream re-use by anyone for commercial purposes,
I am not sure of being quite on target, but I will risk it anyway. This
perspective seems to me to complete the dissemin tool in useful ways.
To inspect what Dissemin is about, just check http://dissem.in .
And if I am totally off base, please tell me. I stand to be corrected,
if needed.
