Prior AmSci Topic Thread:
OA advantage = EA + AA + QB + OA + UA
Ian Rowland's observations, below, are spot-on. He is exactly right that
the OA impact advantage (currently 50-250%) will shrink as we approach
100% OA. Right now we are at 15% OA, and the advantage is in part --
no one can say how large a part -- a *competitive* advantage of the minority
15% OA -- the head-start vanguard -- over the laggard 85% non-OA majority.
That makes it partly a race; and clearly, the race is to the swift and
the battle to the strong. The competitive advantage is *more* reason for an
individual, institution or nation (like the UK) to self-archive right now
(as the RCUK will, we hope, soon be doing).
The OA impact advantage consists of at least the following 6 factors,
three of them (2,3,5) temporary (), three of them permanent (1,4,6)**:
1. *EA*: EARLY ADVANTAGE, beginning already at the pre-refereeing
preprint stage. Research that is reported earlier not only gets its
quota of citations sooner, but the quota goes up, permanently. This
is probably because earlier uptake has a greater cumulative effect
on the research cycle.
2. (AA): (ARXIV ADVANTAGE) the special advantage of self-archiving
specifically in Arxiv for physicists, because it is a central
point of call: OAI-interoperable Institutional Repositories will
supersede this, I am certain, and it will make zero difference which
OAI-compliant IR one deposits in.
3. (QB): (QUALITY BIAS) from self-selection; noncausal: The
higher-quality articles/authors are somewhat more likely to
self-archive in these early (15%) days of self-archiving: this too
will disappear self-archiving approaches 100%, of course).
4. *QA*: QUALITY ADVANTAGE, allowing the high-quality articles to
compete on a level playing field, not handicapped by access
affordability. A permanent effect.
5. (CA): COMPETITIVE ADVANTAGE, for self-archived papers over
non-self-archived ones, in early (15%) days; this will disappear
once once self-archiving nears 100%, of course, but it is an optimal
extra motivator right now, for the low % self-archiving fields.
6. *UA*: USAGE ADVANTAGE: More downloads for OA articles. This too
is a permanent effect.
Of these, only EA, QA, and UA are operative in the few fields that are
already close to 100% OA, such as astrophysics and High Energy Physics.
But everywhere else we are concerned with getting the 15% fields to
climb to 100%, and for them the CA matters a lot too.
So I basically agree with Ian Rowland's comment, and have only two small
replies to add below:

Exactly: The race is to the swift and the battle to the strong. And if
the RCUK adopts its proposed mandate, this will give the UK a substantial
competitive advantage. Once other nations follow suit (as it is to be
hoped that they will do), the competitive advantage will shrink, but the
the Early Advantage, Quality Advantage and Usage Advantage will remain,
and all of research worldwide will be the better off for it.

ISI will almost certainly expand. But there are other players on the
field now too, including free ones, such as citebase, citeseer and google
scholar, and paid ones, such as scopus. So there plenty of new ways to
measure and compare the increased citations that come from OA:

The Competitive Advantage would be gone, but the Early Advantage,
Quality Advantage and Usage Advantage would be going strong. Michael
Kurtz has shown that although articles in a 100% OA field (astrophysics)
do not have longer reference lists, hence do not cite more articles,
they do have three times higher usage rates (UA).
And of course the composition of the references can now be determined by
the merit and quality of the article (QA), not just the affordability
of the journal in which it happened to be published. And whereas the
competitive horse-race (for who self-archives to gain the CA first)
will be over, the cognitive horse-race (for who finds what earlier: EA)
will continue to favour the swift and the strong.
It is fair to say, though, that if the annual 1.5 billion pounds-pounds
worth of potential impact that the UK is currently losing because it only
self-archives 15% of its research output will shrink as other nations'
self-archiving policies catch up. How much it shrinks will then depend
on the true merit of British research and not just the UK's head-start
