Query: Author tracks down the sources of a poetic fragment

I love travel narratives that take me on slow, relaxing journeys to unusual places. This author takes a journey to find the sources of famous poetic fragment, trying to locate Xanadu. This is a pleasant, slow read, and it was intriguing to find that the one part of this search led her back to a neighborhood of her own childhood.
