One of his most important books was London. It was first published in Danish in 1934, in English (as London, the Unique City) in 1937. When this edition was re-issued in 1948, Rasmussen had added two Postscripts: "For English readers only", and "For American readers only". A shorter version was published as a paperback in 1960.
Other influential books by Steen Eiler Rasmussen are Towns and Buildings (1951), and Experiencing Architecture (1959).
It has been stated that every English and American city-planner knows his "Rasmussen".
