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.Comment: 49 pages, 21 figures, 15 tables. Pasteur4OA Work Package 3 report:
