This is a survey paper on recent developments on Simpson’s inequality, Simpson’s quadrature formula and various related results. The following theorem is typical: Let be of bounded variation on . Then
where is the total variation of on .
Except two of the 38 cited papers, all are due to Dragomir et al. Each chapter in this paper is concluded with certain applications of the results for special means of two arguments. It is not mentioned that the first application to special means of Simpson’s quadrature formula is due to the reviewer [Arch. Math. 56, No. 5, 471-473 (1991; Zbl 0693.26005); see also Aequationes Math. 40, No. 2/3, 261-270 (1990; Zbl 0717.26014)].
