Monotone normality

The article surveys recent developments on monotone normality in the context of classical theory. Particular results concern protometrisable, elastic and well ordered (F) spaces, cardinal invariants and compactifications, Borges normal spaces and the extension of continuous functions, Gartsideʹs p-products, topological groups and the structuring mechanism introduced by A.W. Roscoe and the author. A major influence is P.M. Gartsideʹs thesis.
