Abstract: The first paper introduces the notion of an abstract family of languages (AFL) and is concerned with the properties and characterizations of such families. The second is concerned with the independence of the abstract family of languages (AFL) axioms. The third is concerned with families of languages which are usually not AFL but give rise to AFL when closed under homomorphisms.
