Angelou, Maya. I Know Why the Caged Bird Sings. New York: Random House, 1969.
This is the primary source for this paper, and it is a book. This source must be reliable, as it is the primary source document for this subject matter, but it is also the primary autobiography of Maya Angelou, and thus, it serves as the most important work of this paper. The source is also reliable because it is clear, even though Angelou may add some fictional details to this work, that she clearly remembers her youth and growth as a time of change, development, and learning, with racial prejudice and repression as a part of her youth.
