To illustrate how growth in the use of this one license is likely conflated
with overall growth of open access and other factors such as an increas in
OASPA membership, here are the data for the growth in DOAJ including search by
article for 2012:
• 8,461 journals - increased by 1,133 over past year or 3 titles per day
• 4,199 journals searchable by article - up 739 over past year, 2 per
day
• 944,804 articles searchable by article - up 246,258 over past year,
674 per day
• easy prediction: over 1 million articles searchable by article early
in 2013
from: The Dramatic Growth of Open Access 2012 early year-end edition:
http://poeticeconomics.blogspot.ca/2012/12/dramatic-growth-of-open-access-2012.html
The total number of articles searchable by article is impacted or potentially
by several factors:
- additive - new articles published by existing journals
- increasing publication rates for OA journals
- technical - more journals added to the mix (more journals searchable by
article at DOAJ)
- digitization of back issues for journals that have converted from print
What does this mean for interpreting the OASPA chart?
- the growth shown likely mirrors the overall growth of open access.
During this time frame, there has been dramatic growth not only in OA journals,
but also in repositories and their contents.
- the OASPA chart shows a significant upswing in 2008, the year OASPA was
formed as David Prosser points out.
In order to properly assess the data, what is needed is an explanation of the
research method and details about the data itself. Ideally, the full data for
anyone for download and mine.
I find it mind-boggling that scholarly publishers and their associations,
whether traditional or open access, need to have someone point out to them that
if they wish to present data / chart to make a case, they should present their
research method and be prepared to accepted scholarly critique.
