What books stirred up anti-slavery sentiment in the US?

Hundreds of different writings stirred up anti-slavery sentiment, from 1688 when a Quaker petition against slavery circulated in Pennsylvania, to 1865 when the 13th Amendment passed, ending slavery. About 215 of them are reprinted in the recent AMERICAN ANTISLAVERY WRITINGS: COLONIAL BEGINNINGS TO EMANCIPATION, edited by James Basker and published by Library of America.
