I received a free copy from Goodreads.
This is a miscellaneous collection of 366 anecdotes or newspapers excerpts about the US culture and history. Day after day, you'll catch a glimpse of different events. Sure thing that several such events have played a great role in the big History of the US nation and in other countries. It is easy to read thanks to the factual presentation, the author's humor and his rather short and objective comments about the events.
The selection of the subjects depends obviously on the author's preferences, but let's consider that his subjectivity has extracted a variety of events and matters fully aligned with the common culture of his country. For some days, a page is more than enough for an event with low impact or transcendence. For others, you will want to learn more and search on Wikipedia, your favorite newspaper's website or other sources.
Overall, this is all about serendipity. First you let your mind wander between all those stories about events that do not seem connected at all. But eventually you will get the full view. It is like appreciating a painting by an artist using pointillism like Georges Seurat. You need to get close to appreciate the dots and also to put some distance to see the full image, back and forth. And you will see what matters most and what contributed more to build the US culture. The most common topics will be those that define how american people see themselves and also probably how other nations see them: show business, religion, bipartisanship, heroism and the military, fight for civil rights, etc... You can see a stunning example of the massive impact of music in the entertainment industry and the contemporary culture and economy by just reading the January portion. In few pages, you learn about Betsy Cline, Elvis Presley, John Lennon, Carol Channing, Ritchie Valens, Buddy Holly and The Big Bopper ! I'll let you decide if it is an accurate sampling or just a hint that the author might be a big music fan...
However, for some dates, the author uses an easy trick by displaying a date which is not very relevant but helps him to count several years before and/or after the event occurred on this date. That's partially confusing and it erases some credit because what happened on this specific day is diluted with all the causes, consequences and other pieces of context.
