In a catalogue of forthcoming titles for spring 1932, the publisher Stanley Paul lists novels by the following authors:
Nora K Strange
A few names ring a faint bell, but are any of them still in print? I couldn't even find photos of these authors on Google images, apart from one of Edith Nepean talking to Marlene Dietrich in 1949.
However, in another catalogue by a more upmarket publisher, at least one in four of the names is familiar to the modern reader, suggesting that good writing endures more than "popular" fiction.
From my own experience, after a year of looking at thousands of old books, the gulf between art and entertainment is even more tangible than I'd thought.
