Madan helped Sidney Herbert Williams revise his "A Bibliography of Lewis Carroll" (London: The Bookman's Journal, 1924), the first such, into "A Handbook of the Literature of the Rev. C. L. Dodgson (Lewis Carroll)" (London: Oxford University Press, 1931), receiving co-author credit, and published a supplement thereto in 1935. He also edited "The Lewis Carroll Centenary in London" (London: J. &amp; E. Bumpus, 1932), a catalogue of the exhibition.
