Tag 02XJ, permanent. Cite it as [Bourbaki, Tag 02XJ].

Théories spectrales, chapter IV, § 1. Opérateurs compacts sur un espace hilbertien

The canonical inclusion of L1(E;F)\mathscr{L}_1(E; F) in L(E;F)\mathscr{L}(E; F) is of norm ⩽1\leqslant 1 (inequality (9), p. 167).

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
