Now it's time to put two and two together (and this pertains more to the lag between
acceptance and publication: the timing of peer review and revision is another matter):
1. The research community is clamoring for access, particularly those who are denied
access to articles in journals to which their institutions cannot afford to subscribe.
2. In many fields, the most important growth region for taking up and building upon new
findings, hence research progress, is within the first year of publication.
3. The average delay from acceptance to publication for subscription journals is about
6 months (and especially long for arts & humanities journals)
4. Björk and Solomon point out that for Gold OA journals the delay is much shorter:
under 2 months.
5. The delay for Green OA self-archiving is even shorter: zero if self-archiving
is immediate (and even negative if a pre-refereeing preprint has also been made
OA even earlier).
6. Subscription journals say they are in favor of OA, but they need an embargo in order
to keep their subscriptions sustainable.
7. Subscription journals already have a built-in "embargo" because of the 6-month
delay between acceptance and publication.
8. So the 6-12-month Green OA embargoes demanded by STEM fields and even
longer embargoes demanded by arts & humanities journals not only impedes research
progress by denying access during the embargo, but they compound the publisher-end
delays between acceptance and publication.
It makes it possible for researchers to request -- and authors to provide -- immediate
access with one click each as soon as the final, refereed, revised draft is accepted for
publication, irrespective of publication lags or publisher OA embargoes.
