    somebody asked me for the proof of the claim at canonical topology that for a Grothendieck topos H\mathbf{H} we have HSh can(H)\mathbf{H} \simeq Sh_{can}(\mathbf{H}).

    I have added to the entry pointers to the proof in Johnstone’s book, and to related discussion for \infty-toposes. Myself I don’t have more time right now, but maybe somebody feels inspired to write out some details in the nLab entry itself?

    You could copy-paste from my answer here. The proof in the Elephant is for a more general situation.

    Okay, did that.
