Carothers (2000) says: "ℕ is the set of natural numbers (positive integers)" (p. 3)
Mac Lane & Birkhoff (1999) include zero in the natural numbers: "Intuitively, the set $ℕ = {0, 1, 2, ...}$ of all "natural numbers" may be described as follows: $ℕ$ contains an "initial" number 0; ...". They follow that with their version of the Peano Postulates. (p. 15)
