Recall that an Artin group is said of spherical type if its associated Coxeter group is finite. This talk is a general presentation on the automorphism groups of Artin groups of spherical type. We will present known and somewhat lesser-known (because unpublished) results on these automorphism groups, as well as open questions concerning them.
