Well that's cool. One of the uses is to find funding agencies... in this they're not alone. In fact w/biomed topics funding is all important as NIH now has the public archiving (encouragement) policy. See, for example, the MeSH Research Support
. DTIC, NASA and DOE tech reports have contract number, corporate author, etc. Anyway, it's nice to have it for journal articles and conference proceedings.
