1. Hollywood Babylon by Kenneth Anger
This book is chock full of gossip and scandals involving silent film stars. It also features a lot of photographs and other graphics.
2. Silent Stars by Jeanine Basinger
Interesting read. It seems to focus more on the screen presence of the actors and less to do with their private lives. Their most famous roles and films are examined.
3. Marilyn Monroe by Barbara Leaming
This won't satisfy those seeking insight into Monroe's life, but it extensively covers her career and business dealings.
4. Goddess: The Secret Lives of Marilyn Monroe by Anthony Summers
This is a very interesting, absorbing book that delves deeply into Monroe's life, relationships, career, and death.
5. Betty Page Confidential by Stan Corwin Productions and Bunny Yeager
This has several little articles and vignettes about Bettie Page, including one by Bunny Yeager herself! The majority of the book is photographs.
