What I've seen at some UN organizations is a gradual shift towards greater openness of documents that previously were either closed or fee-based. I think, for example, of the ITU, the International Telecommunication Union, the leading UN body dealing with telecom-related matters. Previously many of their documents came at a fairly significant expense, which, by and large, had the effect of excluding many from participating in some of those activities and left it to either governments or corporations involved in telecom issues that had the financial wherewithal to pay for it. There has been a gradual shift--and it's gradual--towards trying to make more material openly available by recognizing that cost for those sorts of government documents represented a significant barrier.
