MWK built a new library in 2011 to accommodate the growing book collection and increased usage by students and teachers. It also houses the computer lab. For many students, the library offers access to a variety of books and a place where they can study quietly for the first time.

With more than 25,000 books, the school offers more books than any other school in Tanzania. The Sir Emeka Offor Foundation of Nigeria presented 4,000 books to the school. TEF supporters continue to donate books.
