In 1939, "Portrait of a Painter. The Authorized Life of Philip de László" by Owen Rutter, written in conjunction with de László, was published. In 2010, Yale University Press published "De László, His Life and Art" by Duff Hart-Davis and Dr. Caroline Corbeau-Parsons. His reputation still remains largely as a society portrait painter, but well numbered amongst his sitters were industrialists and scientists, politicians and painters, men and women of letters and many other eminent, as well as ordinary, people. Family members and a team of editors are compiling a catalogue raisonné published online and in progress. His oeuvre currently numbers almost 4,000 works, including drawings.
