ABSTRACT: A class $\Cal B$ of bitopological structures is a bitopological representation of a class $\Cal C$ of continuous mappings of topological spaces if $\Cal C$ coinsides with the class of all bicontinuous mappings $f:(X,\beta)\longrightarrow (X^\prime,\beta^\prime)$ for all $\beta, \beta^\prime\in\Cal B$. The paper contains a short survey of old author's results and some new results on bitopological representations of classes of metric space mappings.
