"Eminent geographer Yi-Fu Tuan's letters to his friends and colleagues - distilling observations, ideas, and experiences - have carried Tuan's insights, and his reputation, far beyond his chosen field. Culling the most characteristic thoughts and compelling moments from these prized letters, Dear Colleague at long last gives readers near and far the opportunity to share what Tuan's correspondents have already read - and to discover the pleasures of the underlined passages in a book of life at once edifying, entertaining, and exemplary.
