Hi,
If we take the example of BMJ and select a 2007 article on PubMed Central it
does indeed take me to the Highwire site. There is a note on the page that
says "Full Text is available to subscribers, at the Publisher's Site. Free
full text will be available in PMC 36 months after publication, on January
6, 2010". A DOI is also provided which appears to back this up.
However if I select a 2000 issue (i.e. free content) there is no DOI
provided and it "appears" that full text in this case is being delivered
from PubMed Central and not from the Highwire site.
So it looks like the full text for the non-free content is delivered via
their Highwire site, but the free content is being delivered from the PubMed
Central site.
However, as we are subscribers to this title we would be interested in all
the usage generated by this title whether it is free or not. I think! I
won't get into having separate usage statistics for the archive here as I am
sure this will continue to be debated on this list.
Can anyone else throw any light on this?
Cheers
Lesley

Hi,
I might be wrong here but are you not redirected to the BMJ site for the
more recent articles so you actually get the full text from BMJ (or Highwire
I suppose)? The statistcs would show up there then.
Kind regards

Ämne: [lib-stats] PubMed Central and Usage Statistics
Hi,
I don't know whether anyone can help me with this query, but I am confused
about usage statistics on PubMed Central. Many journals that exist in other
places also have a presence on PubMed Central. For example the American
Society for Microbiology journals are available both through Highwire and
through PubMed Central. However according to the FAQs on PubMedCentral PMC
doesn't report use by specific institutions. Does this mean that
institutions have no way of knowing about the usage of titles on PubMed
Central? Does this mean then for e.g. the ASM journals that it is impossible
to have a complete picture of their usage because some of the information is
not available to us...or...is this information collected on their Highwire
site?
At: http://www.pubmedcentral.nih.gov/about/faq.html
"What kinds of usage statistics does PubMed Central provide to participating
journals?
Each publisher has password-controlled access to a web site that has usage
reports for that publisher's journal(s). The reports, updated daily and
aggregated by month, include counts of available articles, total access by
type of page (table of contents, abstract, full-text HTML, PDF, etc.) unique
IP addresses, and most frequently retrieved or cited articles. Line graphs
of each measure supplement the reports. Any report may also be downloaded as
a CSV file, for analysis with a spreadsheet package such as Microsoft Excel.
PMC also provides a CSV file each month, with usage for the month at the
article level. PMC's usage reports generally contain all information called
for in the COUNTER specification, except that PMC does not report use by
specific institutions. NLM's privacy policy prevents the reporting of use at
an individual or organizational level".
Apologies if I've got this totally wrong, but I only started thinking about
this when a lecturer asked me this morning if she had to request an early
article from BMJ through interlibrary loans. I pointed her in the direction
of PubMed Central where she got the article. It started me wondering about
where the usage statistics were gathered for this and all the other titles
that appear on PubMed Central and through other sites.
Cheers
Lesley
