The author of the introduction to the Narrative of Frederick Douglass focuses much more closely on specific events and details throughout the book, and essentially provides the reader with a timeline of Douglass' life. On the other hand, the introduction to Harper's was much more broad and did not include the amount of detail as this one, most likely because of the immense size difference between the two. The tone of the author of the Frederick Douglass introduction was very casual and easy to understand, considering he or she was essentially summarizing the important events of Douglass' life. The subject matter of the two pieces of literature should be taken into account while considering the different writing styles of the two introductions, because it would be impossible for an author to summarize Harper's as closely and specifically as Frederick Douglass' Narrative. Personally, I found the introduction to Frederick Douglass to much easier to understand, and thus a more affective introduction for a reader to understand clearly what the book contained. The introduction to Harper's on the other hand left the reader with a more open ended and less clear cut idea of what the piece of literature would be about.
