In this paper we give a quick overview of the main operators for belief change, in particular revision, update, and merging, when the beliefs are represented in propositional logic. And we discuss some works on belief change in more expressive frameworks. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-23963-2\_6} \end
