Anne Carroll Moore developed a set of standards that she called "The Four Respects":
1. Respect for children.
She wanted children to be treated as individuals and to be treated seriously.
2. Respect for children's books.
Moore was adamant that books for children should be well-written, factually accurate and should not mix fact and fantasy.
3. Respect for fellow workers.
She insisted that the children's library be viewed as an integral and equal part of the complete library.
4. Respect for the professional standing of children's librarians.
Moore felt that the profession must recognize children's librarianship as a professional specialty.
