"The Influence of the National Institutes of Health Public-Access Policy on the Publishing Habits of Principal Investigators"
Nancy Pontika has released her doctoral dissertation, "The Influence of the National Institutes of Health Public-Access Policy on the Publishing Habits of Principal Investigators."
Here's an excerpt:
The NIH public-access policy did not cause either an increase in the PIs' open-access awareness or a change in their publishing habits. The open-access advocates were supporters of the immediate free access to scientific information before the policy and provided their manuscripts free-of-cost before the policy’s mandate. The non-open-access advocates choose their publications based on quality criteria such as the journal’s prestige, impact factor, speed of publication and the attracted audience, while the article’s open-access availability is considered to be a plus. Furthermore, since a large number of journals comply with the NIH-policy, the participants did not have to change their publishing habits.
