The Pulitzer Prize-winning author of "The Power Broker" and "The Years of Lyndon Johnson," Robert A. Caro, is known for his meticulously researched, thoroughly reported biographies.

His voluminous works are celebrated, as is his dedication to his craft: Caro and his wife Ina have outright moved their residence multiple times in service of his books, so that they could experience the world as the subjects of his books might have. Collectively, they've spent tens of thousands of hours poring over documents, conducting interviews, and much more — all in the service of thoroughly, accurately portraying the lives of his books' subjects.

Which is why Caro's latest book, "Working: Researching, Interviewing, Writing," is so particularly fascinating.
