Written in 1922, Nella Braddy's Young Folks' Encyclopedia of Etiquette is filled with all kinds of useful knowledge for young folks in the 1920s.

Of course, accepted etiquette changes over time, depending on many factors. For instance, according to this passage entitled "The Child's Rights," it was considered harmful to the child's psyche to brag incessantly about his or her accomplishments in front of the child. Today, such behavior might be construed in a much different way.

The rules of decorum related to dress and modesty have obviously changed since 1922. Check out how a young lady was expected to dress for a day at the beach. Hard to imagine what a similar book would say today.
