Grazier left the University of Chicago in 1956, and relocated to
Birmingham, Michigan, where she took on the role of head librarian at
Derby High School. There she stayed until 1961 when she moved to the position of head librarian at
Groves High School. Public high school librarianship was not the only thing that Grazier was doing with her career during this time period though; She was also a visiting instructor for the
University of Michigan's Library Science program during the summers. Grazier is known in the library field for her work in expanding the role of school library media specialist. In the 1960s the librarian's traditional role was that of a storyteller and provider of space for students to read recreationally. Her practice and writings led her to branch out to becoming directly involved in the instruction, to be embedded in the classroom and to collaborate with schoolteachers in developing their curriculum. So that in the 1970s, the role evolved into that of collaborator and teacher of library skills which included the assessment of research sources. In 1965, Grazier made a career move, becoming a member of the
Wayne State University faculty as an associate professor and eventually was promoted to a full time professor in 1972. In this role she was able to apply her knowledge of school libraries, specifically in the area of school librarian leadership in the library curriculum and its vital role in the learning process. In both her teaching and in the articles that she published, there is a strong recurring theme, and that is the importance that she places on the role of the school librarian. She believed that school librarians should really understand and execute both the 'theory of the curriculum and also the instructional technology'. Grazier worked as a professor at Wayne State University until she retired in 1983. After Grazier's death in 1999, her husband created a scholarship in her name, The Margaret Hayes Grazier Endowed Scholarship Fund, at the school in which she spent the largest portion of her career, Wayne State University. The scholarship is presented yearly to students in the Library and Information Science Program who meet academic, character and leadership qualifications, in addition to financial need. They must also be pursuing a career in Grazier's specialty of school library media or youth services. ==Extra-curricular activities==
