We investigate the group Pic(DM) of isomorphism classes of invertible objects in the derived category of O-modules for a commutative unital ringed Grothendieck topos (E;O) with enough points. When the ring Op has connected prime ideal spectrum for all points p of E we show that Pic(D M ) is naturall
