The Author provides very good coverage in the areas with which she and her network of peers were familiar. But belying the book's title, there are huge gaps in her knowledge -- for which she does allow and begs forgiveness.
Her field research and travels in parts of Europe, the Middle East and Southeast-Asia places greatly influence -- perhaps too much -- her coverage of beekeeping in these areas. She provides good general coverage of traditional hives in history and in current usage.
However, her research pretty much stops at 1998 or so, and thus has little to say about the recent proliferation of top bar and other unframed hives in "emerging economies" and in the West.
Substantially missing are discussion of post-Langstroth developments in hive design and beekeeping methodology. For instance, the early-mid 20th Century writings of Abbé Émile Warré and later non-Rationalist trends in beekeeping are not mentioned. Warré's Ruche Populaire (People's Hive) has been rescued from a half-century of obscurity, and is gaining adherents in the post-Rational beekeeping movement of the 21st Century.
So this book has excellent coverage of beekeeping's history, proving that humans have been doing it for an awfully long time; yet it is a dated work of pre-internet scholarship, and so its limitations must be kept in mind.
