What has been the impact of some open access journals and open access archiving on the STM market?
• Some journals report that delayed open access increases subscriptions. The increase seems to be a result of the heightened visibility, impact, and usage of the journal’s articles. • In physics, where nearly 100 percent of new articles are freely available in an open access archive, subscription-based journals continue to thrive. • The NIH plan essentially calls for the open-access archiving of refereed articles or post-prints after a six-month delay. Elsevier permits its authors to deposit their manuscripts in open-access archives, with no delay at all. Moreover, Elsevier allows open-access archiving of the final version of the text, after both peer review and copy editing. • More than 180 subscription-based journals currently make their contents openly available after an embargo period. Although the impact of this on their subscription bases has not been publicly reported, one might assume that if the impact was negative, they would have discontinued the practice.
