26. NIH Public Access Policy
Newly Enacted
The Policy implements Division G, Title II, Section 218
of PL 110-161 (Consolidated Appropriations Act, 2008)
which states:
The Director of the National Institutes of Health shall
require that all investigators funded by the NIH submit
or have submitted for them to the National Library of
Medicine’s PubMed Central an electronic version of
their final, peer-reviewed manuscripts upon acceptance
for publication, to be made publicly available no later
than 12 months after the official date of publication:
Provided, That the NIH shall implement the public
access policy in a manner consistent with copyright law.
27. Motive behind the Policy
http://publicaccess.nih.gov/
Ensure public access
Publicly funded
Advance science and improve human
health
Not open access - not immediate
28. Who does it apply to?
Directly funded by an NIH grant or cooperative
agreement active in Fiscal Year 2008 (October
1, 2007- September 30, 2008) or beyond
Directly funded by a contract signed on or after

articles, from academic publishers, professional
societies, preprint repositories, universities and other
scholarly organizations”

35. Citation Analysis
Research productivity measures
Grant awards, grant dollars
Publications, cited references
Strengths vs weaknesses
History, quantifiable, broad view
Homographs (author disambiguation),
cronyism, negative citations, lack of tools
