Title: On the deformation of rings and algebras, V: Deformation of differential graded algebras

From the introduction:

In this paper we consider the deformation theory of differential graded modules (DGM's) and differential graded algebras (DGA's), where only the differential varies, the underlying module or algebra structure remaining fixed. At the outset we consider only individual modules or algebras and afterwards we examine deformations of sheaves.

Note: this will appear in the Stasheff Fest volume.
