Forwarded from BOAI Forum: Important corrections from Professor Wilson
regarding the true rate and proportion of spontaneous self-archiving
of article full-texts. This rate and proportion is almost certainly
over-estimated by the Driver Study -- but that only reinforces its
recommendation that self-archiving needs to be mandated. -- SH

One of the items in Peter Suber's OA News made me raise my eyebrows:
http://www.earlham.edu/~peters/fos/2007_04_29_fosblogarchive.html#5931097067404812219
he quotes from the DRIVER report that:
"On average, the estimated percentage of research output of 2005 deposited in
the digital repositories is 37%"
This, of course, is a Europe-wide study and perhaps the success of repositories
varies considerably from country to country. In the study I did last year of
the UK repositories, I estimated that they contained something in the order of
3% of the research output from the UK in 2004 - I would be very surprised if
they had improved tenfold in one year.
Looking further into the report I see that only 57 UK institutions were invited
to respond to the investigation and, of these, only 51% responded (and we can
assume that those who respond are most interested in the subject under
investigation). The report also notes that:
"On average a digital repository contains in total 8,984 items."
Meaning, of course, items of all kinds, not solely journal papers. Again, this
figure contrasts starkly with the situation I found in the UK, where, the
combined total of journal papers in ALL of 21 repositories available for study
was 9,739 - an average (meaningless, of course, as any average of a skewed
distribution) of 464 items per repository. In fact the totals by institution
ranged from 2 items in total to 5,139 items, with a median value of 78 items.
A comparison of these data with those form the DRIVER report still leaves me
puzzled :-)
