I agree with Simeon Warner that funding agencies should seriously consider a requirement that all publications resulting from research supported by such agencies must be deposited in open-access repositories.
This raises a question that hasn't been discussed recently by members of this Forum: Is there any funding agency, other than, I believe, the Danish Research Centre for Organic Farming (DARCOF), via it's Organic Eprints archive (see: http://orgprints.org/ ), that has done both of these: a) mandates open access to the results of research funded by that agency, and, b) has established it's own knowledge-transfer-oriented eprints archive? For example, such an archive could be used (instead of, or in addition to) the grantees' own preferred institutional (or, discipline-based) open-access repository. A reminder: Peter Suber has developed a draft version of an open-access policy for foundation research grants, and has discussed some of the issues that need to be considered: Model Open-Access Policy for Foundation Research Grants Draft 8. March 7, 2004. http://www.earlham.edu/~peters/fos/foundations.htm An example of one of the issues that Peter has considered (see: "Term 10. When the open-access condition is violated): "If compelling recipients to repay the grant is too strong, and compelling late open-access dissemination is too weak, then foundations might consider some intermediate options. For example, the foundation could reserve some additional "incentive funds" to be released only when the recipient has provided open access to works based on previous funds. Or the foundation could simply make non-complying recipients ineligible for future grants". Jim Till University of Toronto
