"These titles are a great way to gain insight into the episodes and the social and cultural times in which the series is set. Like the set and costume design, the literary choices of the show really add a stamp of authenticity. Dipping into these classics is also a great way to help with withdrawals while waiting for new episodes to air.Some of the titles are featured prominently in the series and others are mentioned in passing. Remember the book Sally read with her grandfather at bedtime? The book on Japanese culture the agency was told to read? The scandalous book the ladies passed between each other in secret? You can find all these and more!"
