The premise of this book is so exciting - a front row seat for the 20th century, the real, day by day unfolding and confusion of events we now see through a fog of myth and nostalgia. But it didn't really deliver, perhaps because Elborough chose to include entires that mentioned incidents and facts, so as to fit in as many historical happenings as he could, rather than focussing on fewer events, but giving us a wider cross-section of reactions to them, with a little more exploration of the emotional and psychological impact they had on people from different walks of life. It's a big ask to deliver something like that, but wouldn't it be more worthwhile? A chronology does for getting a picture of the occurrences of the century; a collection of diaries and letters might be better used going deeper into each episode.
Another thing which would have been helpful is a little more detail about each diarist, e.g where they're from, their occupation and age. In that way, their views would have been succinctly contextualised, assisting us in understanding their reactions.
It is an interesting read, with one or two surprising, funny and illuminating moments, but the view of events it provides is, overall, superficial.
