Well-known and bit overrated, but an excellent treatment of Osborn's technique of brainstorming. This book has probably had more influence than any other in stimulating interest in idea production among professional people in business organisations.
Discusses not only brainstorming , but also Osborn's thinking about creativity. It is written in an expansive, early 1950's style and tends to reference opinion rather than science, but it strikes a responsive chord in some readers. It was quite influential, as was Osborn himself in the upsurge in the study of creativity in the 1950s.
