Durell's textbooks were hugely successful from the 1920s, and by 1935 his publisher, G. Bell & Sons, was claiming:

*There can indeed be few secondary schools in the English-speaking world in which some at least of Mr Durell's books are not now employed in the teaching of mathematics*.

He collaborated on books with masters from other schools, such as R. M. Wright of Eton, A. W. Siddons of Harrow, C. O. Tuckey of Charterhouse, Alan Robson of Marlborough and G. W. Palmer of Christ's Hospital.

Durell's books cover all areas of school mathematics, including algebra, calculus, mechanics, geometry, and trigonometry, and include:

*Elementary Problem Papers* (Arnold, London, 1906)
*Readable Relativity* (G. Bell & Sons, 1926)
*The Teaching of Elementary Algebra* (G. Bell & Sons, 1931)
*General Arithmetic (G. Bell & Sons, 1936)**
*- Elementary Geometry
* (G. Bell & Sons, 1948) First published 1925*
