One reviewer opines that this book is of limited use because the compiler collected only what he found interesting. By that standard, Johnson's Dictionary would get a poor Amazon review.
Although I can agree with other reviewers that there is some inconsequential fluff here, I found this book highly entertaining and mesmerizing, even if some of the arcana in it was of little direct interest to me. I loved the chart of US Presidents that included not only their ages when they took office, but whether they were left-handed, red-headed, whether they had facial hair, and whether they died on July 4. I loved the list of unusual deaths of Burmese kings (one, Nandabayin, laughed himself to death when a visiting European merchant told him that Venice was a free state without a king). I loved the recitation of the British Riot Act of 1714. I loved the list of the 33 degrees of Freemasonry hierarchy. I loved the schematic diagram of Dante's Inferno.
What use is this book to you if you're not a reference librarian or a triviaholic? Virtually none. So what? I loved it, and only wish it were much, much longer. Almanac length would be a start.
