This one was hard to rate. It's basically a history of books and libraries of the ancient Greco-Roman world. It started off fairly interesting but my interest didn't seem well matched to the length of the book, and it wasn't a long book. So I'm not sure whether the later chapters on Roman libraries and early Christian libraries were drier or more repetitive or what, but my interest flagged a little. I considered dropping down to 2.5 stars but thought that might be a bit harsh.
