Anthony Stevens has written excellent books on topics associated with Jungian perspectives, including  Archetype, Revisited: An Updated Natural History of the Self or  Private Myths: Dreams and Dreaming (Penguin psychology)  and writes an introduction to Jung which is second only to that of Storr.

Each introduction has a great content and index included in this single volume and each introduction is a perfect companion to one another. The writing style of each author is highly complementary, providing for a good continuity in pace, style, and content.
