I'd also recommend a quick read about the technology of the time. Rotary phones, typewriters, cassette tapes. 1973 was the year the USA launched its first space station Skylab. Microwaves finally became affordable to the everyman. The very first arcade games are rolling out across the country. It's also two years until the first digital camera, meaning all photos have to be developed in a dark room. Perhaps most Sci-fi of all were the first pocket calculators and LCD/LED screens.
