Package 3 report: Open Access policies

The PASTEUR4OA project analyses what makes an Open Access (OA) policy
effective. The total number of institutional or funder OA policies
worldwide is now 663 (March 2015), over half of them mandatory.
ROARMAP, the policy registry, has been rebuilt to record more policy
detail and provide more extensive search functionality.

Deposit rates were measured for articles in institutions' repositories
and compared to the total number of WoS-indexed articles published
from those institutions. Average deposit rate was over four times as
high for institutions with a mandatory policy. Six positive
correlations were found between deposit rates and (1) Must-Deposit;
(2) Cannot-Waive-Deposit; (3) Deposit-Linked-to-Research-Evaluation;
(4) Cannot-Waive-Rights-Retention;  (5) Must-Make-Deposit-OA (after
allowable embargo) and (6) Can-Waive-OA.

For deposit latency, there is a positive correlation between earlier
deposit and (7) Must-Deposit-Immediately as well as with (4)
Cannot-Waive-Rights-Retention and with mandate age. There are not yet
enough OA policies to test whether still further policy conditions
would contribute to mandate effectiveness but the present findings
already suggest that it would be useful for current and future OA
policies to adopt the seven positive conditions so as to accelerate
and maximise the growth of OA.
