I'm interested in a history of these terms, and wondered if anyone knows where I might find such a thing.
The first mention I can find for excludability is a 1957 law journal paper referring to a court case (inaccessible to me).
The earliest citation I've been able to find for rival goods is Chapman (1909), but mostly I see economics papers cite more recent textbooks (1980-2000).
Tangible goods seems to be a legal term, for which I can find the first mention in an 1889 law journal (which I also can't acccess).
The earliest reference I can find for durable goods is John Law (1750).
A secondary goal might be finding an authoritative source where all of these terms are tied together for the first time.
