• (psi)over-bar-derivatives
• locally integrable function
• functions of exponential type

The aim of this paper is to extend (psi, beta)-derivatives to (psi) over bar -derivatives for locally integrable functions on the real line and then investigate problems of approximation of the classes of functions determined by these derivatives with the use of entire functions of exponential type.
