Objet : Re: Full-Text Useage Statistics: Open Access vs. Firewalled
Jan,
I do not think you have enough data yet for your titles. You are
comparing onw group of articles in an open environment with different
articles in a closed environment.
Stevan is correct that for the same articles, the open environment is
much more used, at least for ArXiv. This is compatible with recently
collected preliminary data from this university which shows very low
print and quite low electronic use from the journals whose articles are
in fields covered by arXiv, even though that area of coverage is a major
research subject here.
I can think of many sources from which relevantdata could potentially be
gathered. E.G., access for Highwire titles the month before and the
month after the access is open to the public.
What Biomednet needs to prove to me is that its articles are of
first-rate quality. I do not care much about use of lesser material,
from any source, paid or unpaid, just because it's there. I care about
use of excellent material, which is what the scientists really need.
It's excellence in scientific quality that matters most--only then comes
ease of availability to it.
If you prove able to arrange for both, you will have solved the problem.
-- Best wishes, David
