Varian, "Microeconomic Analysis" was the standard grad econ text until
recently. In the 3rd edition p. 414, starting the chapter titled
"public goods", it gives this definition:
"We say that a good is excludable if people can be excluded from
consuming it. We say that a good is nonrival if one person's
consumption does not reduce the amount available to other consumers. ...
Goods that are not excludable and are nonrival are called public goods."
