review text: The authors describe a mixed finite element method which allows simultaneous approximation of the transverse deflection, the curvature tensor and the bending and twisting moments. Existence and uniqueness theorems together with error estimates are given in the spirit of Brezzi, Ciarlet and Raviart. There are five references given here to papers with virtually the same title by the same authors with much overlapping material. Unfortunately the authors do not point out what is new in the present work nor how it improves on their previous work.
