Codebook
A detailed account of the methodologies used and choices made in building COMETS is found in Lynne G. Zucker, Michael R. Darby and Jason Fong, “Communitywide Database Designs for Tracking Innovation Impact: COMETS, STARS and Nanobank,” National Bureau of Economic Research Working Paper No. 17404, September 2011, available here or at http://www.nber.org/papers/w17404.
In complement to this basic source, the codebook contains names and descriptions of the fields in the COMETS data set.
The codebook is organized in two main sections, ordered as follows:
- Section 1: Patents
- Section 2: Grants (NSF and NIH)
Definitions of codes used in the data can be found in additional tabs in this document. The link in the "Reference Sheet" column of the codebook will go to the tab containing information for that particular field.
