With all the emphasis on immediate open access, I'm wondering - how up
to date is google scholar?
A quick search by publication year yields the following:
2001: 62,000 items
2002: 68,600 items
2003: 63,700 items
2004: 8,060 items
While it is possible that 2004 statistics will not be complete due to
publishing delays, this does suggest to me that there is a delay in
google scholar harvesting - whether of open access or
subscription-based resources, or both, is hard to say of course. I do
think this data suggests that if there is one place to look for OA
materials at the moment, it is not google scholar.
My own searching confirms this suspicion - I am finding that if a
needed item is not found in google scholar, then an open access copy
may well still be found through a regular web search.
hope this helps,
Heather Morrison
