Preface, a Gwinnett-based organization that provides tutoring service in several Gwinnett schools, donated more than 200 books to Graves Elementary Schools’ library on Thursday. Several books included in the donation are written in languages spoken by students who come from households where English is not the primary language spoken and many feature women and people of color. School officials said the donation will be beneficial for the school because students will be able to see stories that reflect their heritages in the library.
