An Essay on Typography was first published in 1931, instantly recognized as a classic, and has long been unavailable. It represents Gill at his best: opinionated, fustian, and consistently humane. It is his only major work on typography and remains indispensible for anyone interested in the art of letter forms and the presentation of graphic information.

This manifesto, however, is not only about letters — their form, fit, and function — but also about man's role in an industrial society. As Gill wrote later, it was his chief object "to describe two worlds — that of industrialism and that of the human workman — and to define their limits."

His thinking about type is still provocative. Here are the seeds of modern advertising: unjustified lines, tight word and letter spacing, ample leading. Here is vintage Gill, as polemical as he is practical, as much concerned about the soul of man as the work of man; as much obsessed by the ends as by the means.
