Given the results of this article and the very narrow scientific
interest in high energy physics articles, what is the point of SCOAP3
... other than to absolve authors of any responsibility for the costs
of maintaining the peer-review system, and to maintain the enormous
disparity in subscription costs between commercial and non-profit
high energy physics journals?

Gentil-Beccot, Anne; Salvatore Mele, Travis Brooks (2009) Citing and
Reading Behaviours in High-Energy Physics: How a Community Stopped
Worrying about Journals and Learned to Love Repositories

This is an important study, and most of its conclusions are valid:

(1) Making research papers open access (OA) dramatically increases
their impact.

(2) The earlier that papers are made OA, the greater their impact.

(3) High Energy Physics (HEP) researchers were among the first to
make their papers OA (since 1991, and they did it without needing to
be mandated to do it!) 

(4) Gold OA provides no further impact advantage over and above Green
OA.
However, the following caveats need to be borne in mind, in
interpreting this paper:

(a) HEP researchers have indeed been providing OA since 1991,
unmandated (and computer scientists have been doing so since even
earlier). But in the ensuing years, the only other discipline that
has followed suit, unmandated, has been economics, despite the
repeated demonstration of the Green OA impact advantage across all
disciplines. So whereas still further evidence (as in this paper by
Gentil-Beccot et al) confirming that OA increases impact is always
very welcome, that evidence will not be sufficient to induce enough
researchers to provide OA; only mandates from their institutions and
funders can ensure that they do so.

(b) From the fact that when there is a Green OA version available,
users prefer to consult that Green OA version rather than the journal
version, it definitely does not follow that journals are no longer
necessary. Journals are (and always were) essentially peer-review
service-providers and cerifiers, and they still are. That essential
function is indispensable. HEP researchers continue to submit their
papers to peer-reviewed journals, as they always did; and they
deposit both their unrefereed preprints and then their refereed
postprints in arxiv (along with the journal reference). None of that
has changed one bit.

(c) Although it has not been systematically demonstrated, it is
likely that in fields like HEP and astrophysics, the journal
affordability/accessibility problem is not as great as in many other
fields. OA's most important function is to provide immediate access
to those who cannot afford access to the journal version. Hence the
Early Access impact advantage in HEP -- arising from making preprints
OA well before the published version is available -- translates, in
the case of most other fields, into the OA impact advantage itself,
because without OA many potential users simply do not have access
even after publication, hence cannot make any contribution to the
article's impact. 

(d) Almost no one has ever argued (let alone adduced evidence) that
Gold OA provides a greater OA advantage than Green OA. The OA
advantage is the OA advantage, whether Green or Gold. (It just
happens to be easier and more rigorous to test and demonstrate the OA
advantage through within-journal comparisons [i.e Green vs. non-Green
articles] than between-journal comparisons [Gold vs. non-Gold
journals].)

EXCERPTS: from Gentil-Beccot et al:

ABSTRACT: Contemporary scholarly discourse follows many alternative
routes in addition to the three-century old tradition of publication
in peer-reviewed journals. The field of High- Energy Physics (HEP)
has explored alternative communication strategies for decades,
initially via the mass mailing of paper copies of preliminary
manuscripts, then via the inception of the first online repositories
and digital libraries.

This field is uniquely placed to answer recurrent questions raised by
the current trends in scholarly communication: is there an advantage
for scientists to make their work available through repositories,
often in preliminary form? Is there an advantage to publishing in
Open Access journals? Do scientists still read journals or do they
use digital repositories?

The analysis of citation data demonstrates that free and immediate
online dissemination of preprints creates an immense citation
advantage in HEP, whereas publication in Open Access journals
presents no discernible advantage. In addition, the analysis of
clickstreams in the leading digital library of the field shows that
HEP scientists seldom read journals, preferring preprints instead....

...

...arXiv was first based on e-mail and then on the web, becoming the
first repository and the first "green" Open Access5 platform... With
the term "green" Open Access we denote the free online availability
of scholarly publications in a repository. In the case of HEP, the
submission to these repositories, typically arXiv, is not mandated by
universities or funding agencies, but is a free choice of authors
seeking peer recognition and visibility... The results of an analysis
of SPIRES data on the citation behaviour of HEP scientists is
presented... demonstrat[e] the "green" Open Access advantage in
HEP... With the term "gold" Open Access we denote the free online
availability of a scholarly publication on the web site of a
scientific journals.... There is no discernable citation advantage
added by publishing articles in "gold" Open Access journals...

...

7. Conclusions

Scholarly communication is at a cross road of new technologies and
publishing models. The analysis of almost two decades of use of
preprints and repositories in the HEP community provides unique
evidence to inform the Open Access debate, through four main
findings:

1. Submission of articles to an Open Access subject repository,
arXiv, yields a citation advantage of a factor five.

2. The citation advantage of articles appearing in a repository is
connected to their dissemination prior to publication, 20% of
citations of HEP articles over a two-year period occur before
publication.

3. There is no discernable citation advantage added by publishing
articles in "gold" Open Access journals.

4. HEP scientists are between four and eight times more likely to
download an article in its preprint form from arXiv rather than its
final published version on a journal web site.

Taken together these findings lead to three general conclusions about
scholarly communication in HEP, as a discipline that has long
embraced green Open Access:

1. There is an immense advantage for individual authors, and for the
discipline as a whole, in free and immediate circulation of ideas,
resulting in a faster scientific discourse.

2. The advantages of Open Access in HEP come without mandates and
without debates. Universal adoption of Open Access follows from the
immediate benefits for authors.

3. Peer-reviewed journals have lost their role as a means of
scientific discourse, which has effectively moved to the discipline
repository.

HEP has charted the way for a possible future in scholarly
communication to the full benefit of scientists, away from over three
centuries of tradition centred on scientific journals. However, HEP
peer-reviewed journals play an indispensable role, providing
independent accreditation, which is necessary in this field as in the
entire, global, academic community. The next challenge for scholarly
communication in HEP, and for other disciplines embracing Open
Access, will be to address this novel conundrum. Efforts in this
direction have already started, with initiatives such as SCOAP3...
