The notion of integro-differential algebra brings together the usual derivation structure with an algebraic version of indefinite integration and evaluation. We construct the associated algebra of integro-differential operators (used for modeling Green's operators for linear boundary problems) directly in terms of normal forms. For polynomial coefficients, we can use skew polynomials, defining the integro-differential Weyl algebra as a natural extension of the classical Weyl algebra in one variable. Its algebraic properties and its relation to the localization of differential operators are studied. Fixing the integration constant, we regain the integro-differential operators with polynomial coefficients
