Abstract: We study several questions related to differentiation of integrals for Besov spaces relative to the basis $\mathcal {R}$ of arbitrarily oriented rectangular parallelepipeds in $\mathbb {R}^{d}$, $d \geq 2$. We improve on positive and negative differentiation results of Aimar, Forzani, and Naibo and on capacitary and dimensional bounds for exceptional sets of Naibo. Our main tool in obtaining these improvements involves showing that bounds for the Nikodym maximal operator can be used to deduce boundedness properties of the local maximal operator associated to $\mathcal {R}$.
