What is the author's style in Voices from the Harlem Renaissance by Nathan Irvin Huggins?

With the array of authors represented in the book, there are an equal number of writing styles. There are also many different topics, and most readers will find they are interested in some, but not all. The selections range from politics to art. The writings are sometimes hopeful in tone and sometimes dark. It should be noted that the majority of the writers use the word "Negro" or "colored," which were arguably the most correct and generally accepted terms of the day.
