In 1986, Marlene Laskey interviewed John Lautner for the University of California, Los Angeles (UCLA) Oral History Program. Her 6-1/2 hour interview was printed by UCLA with the title Responsibility, Infinity, Nature. Ms. Laskey has since died and access to the book has been limited.
However, you can read it. It is available through the Internet Archive, an online library for researchers, historians, and scholars. The library maintains copies of the book in several different formats. You can read it online or download it. But you cannot use material from this book for other projects to be sold or distributed to the public without obtaining permission from UCLA. The material is still under copyright protection.
