Re: Study Identifies Factors That Could Lead to Cancelled Subscriptions

As I hoped, a publisher has come up with some real figures about 
the effect of going OA after a short embargo.  See below from 
PNAS (forwarded with Diane's permission).

I wonder whether there are other publishers on this list who have 
statistics they could share?

Subscriptions

Hi Sally,

In 2000, we were free after one month. We lost 11% of our paid 
subscribers in 2001, higher than the industry average, and we 
switched to 6 months in 2002. The move did not stem the loss in 
subscribers but it was reduced to 9% in 2002. We do not have hard 
data to show a causal effect of our one month policy, but the 
correlation certainly motivated a change.

Best,
Diane
