 In general, the literature on unawareness has been rapidly growing. Bradley (2017) and Steele and Stefánsson (forthcoming-b) are new in-depth treatments of this topic within philosophy. Schipper maintains a bibliography on unawareness, mostly with papers in economics and computer science, at \url{http://faculty.econ.ucdavis.edu/faculty/schipper/unaw.htm}.
