The first section of the book, "Family and History," includes Morrison's writings about her family, Black women, Black history, and her own works. The second section, "Writers and Writing," offers her assessments of writers she admires and books she reviewed, edited at Random House, or gave a special affirmation to with a foreword or an introduction. The final section, "Politics and Society," includes essays and speeches where Morrison addresses issues in American society and the role of language and literature in the national culture.
Among other pieces, this collection includes a reflection on 9/11, reviews of such seminal books by Black writers as Albert Murray's South to a Very Old Place and Gayl Jones's Corregidora, an essay on teaching moral values in the university, a eulogy for James Baldwin, and Morrison's Nobel lecture. Taken together, What Moves at the Margin documents the response to our time by one of American literature's most thoughtful and eloquent writers.
