The Mãe Preta library includes two aspects. First, a collection of books donated for the project. Secondly, the marking of those books in the institute's permanent collection written by black female authors, and where black women, feminism or themes related to women's studies appear.

The children's library includes titles where black children or Afro-Brazilian culture are the main themes.

The books are available for local consultation during opening hours. The project is also open to new donations during the exhibition period.
