Book excerpt: The second volume within this series presents more than fifty series characters within pulp fiction, selected to represent four popular story types from the 1907-1939 pulps--scientific detectives, occult and psychic investigators, jungle men, and adventurers in interplanetary romance. Some characters--Tarzan, John Carter of Mars, Craig Kennedy, Anthony (Buck) Rogers--became internationally known. Others are now almost forgotten, except by collectors and specialists.
