How can I rate non-fiction that is truly letters from the 1940s and 1950s between several people, mainly two, about the quest to find rare books at an affordable price? I don't think a star rating necessarily belongs on nonfiction of this variety, but I will say the audiobook is very well narrated and brings to life the humor and emotion of these original letters. 

As someone born in the 80s, much of the style of life described in these letters is something I have never experienced. But in some way, there is a corollary here between old fashioned letters and the magic of written conversation when you are getting to know someone, be it letters, emails, text messages, or another format. 

I think this epistolary collection is a joyful slice of life in which all of us who love reading can find something to relate to.
