Source

The Medical Innovation data were stored in file cabinets in a basement building at Columbia University. Ron Burt (1987) acquired an NSF grant to develop network diffusion models and retrieve the original surveys and enter them into a database. He distributed copies of the data on diskette and sent one to me, Tom Valente, and I imported onto a PC environment.
