Abstract: For a scheme $ X$, we construct a sheaf $ \mathbf{C}$ of complexes on $ X$ such that for every quasi-compact open $ U \subset X$, $ \mathbf{C}(U)$ is quasi-isomorphic to the Hochschild complex of $ U$ (Lowen and Van den Bergh, 2005). Since $ \mathbf{C}$ is moreover acyclic for taking sections on quasi-compact opens, we obtain a local to global spectral sequence for Hochschild cohomology if $ X$ is quasi-compact.
