Routledge Library Editions: Sleep and Dreams (9 Volumes) brings together as one set, or individual volumes, a small series of previously out-of-print titles, originally published between 1935 and 1988. An eclectic mix, the set looks at sleep and dreams from a number of different perspectives, including philosophy, psychoanalysis and science. It includes a sourcebook, which reviews areas of sleep and dream research, and a dictionary to help people interpret their own dreams.
