We consider Bessel systems in a Banach space and study their operator and projective characteristics. Using an operator construction for the continuation of the system, we prove an analog of Schur's theorem on continuable systems.
Keywords: Bessel system, Banach space, continuation of a Bessel system, linear operator, model space, Schur's theorem.
