Addendum and correction to ''A combination theorem for negatively curved groups''
The purpose of this note is to give an algebraic formulation of the main theorem in our paper [ibid. 35, 85-102 (1992; Zbl 0724.57029)] and to correct an omission in a corollary. We also state a slightly stronger version of the combination theorem in the last section.
