From an internal email (with permission)
[The NRC Senior Executive Committee] SEC has established a policy making it mandatory, starting in January 2009, for NRC institutes to deposit copies of all peer-reviewed publications (articles, proceedings, books, book chapters) and technical reports in [the forthcoming NRC Institutional Repository, to be called] NPArC. The SEC has also approved an update to NRC Form 22 Licence to Publish (Crown Copyright) that will explicitly state NRC’s intention to deposit these publications in NPArC.
As this blog is by no means an official source of information about my organisation, if you have any questions I ask that you go through regular NRC or CISTI communications channels.
UPDATE 2008-07-23: There is now an official press release from CISTI.
