Modern literary fiction was often not well-suited to illustration, for example the introspective novels of E. M. Forster and Virginia Woolf. Illustrations were used on book covers to attract buyers, but not used within the novel. Similar to the period before 1836, illustrations were not commissioned for new books, but were commissioned for established classics, usually for a limited luxury edition. Serious novels are not illustrated, and illustrated fiction is generally associated with serialized or short fiction that is published in popular but not intellectually prestigious magazines. Children and comics readers became the only fiction readers whose fiction was generally illustrated.
