1776 through 1976 reviewed with engaging, informative text, accompanied by black and white photographs and illustrations - many color plates on glossy paper; table of contents according to year; topical index.
I'm the kind of kid who would read a book like this for fun. In fact, I did read this book for fun. I don't know that I ever sat down and read it cover to cover, but I did skip through it and read interesting bits and pieces from it often enough that I must have eventually read the whole damn thing.
The book was set up so that for each year there was a paragraph for each day explaining each event the author deemed important in U.S. history.
Once in elementary school (fourth grade, I think, in the early 1980s) I even won a radio contest using this book. The DJ asked what important event had happened on this day in whatever year. I grabbed my trusty Bicentennial Almanac, found the correct entry and called the radio station. When I read the blurb to the DJ, I wasn't even really sure what I was reading, but got the answer right and got a bunch of goodies. (I think that was the Dr. Pepper gift package, including a small duffel bag the color and design of a Dr. Pepper can and an AM/FM radio that looked just like a Dr. Pepper can.) The historic event was a woman had been nominated to run for president.
