Here's a Black History Month resource from Virtual Library Cat:
"On January 31, 1865, the House of Representatives passed the 13th Amendment to the U.S. Constitution that abolished the institution of slavery in the entire country. Having already passed the Senate, the amendment was on its way to the states for ratification. The fascinating story of the proposed and adopted methods for ending American slavery, with a timeline, biographies of the major players, and links to articles and documents, can be found at the 13th Amendment Site--"The End of Slavery: the Creation of the 13th Amendment." What makes this site especially engaging are the primary source materials--news items, editorials, illustrations, cartoons--taken directly from the pages of Harper's Weekly, described as "the leading American illustrated newspaper in the second half of the nineteenth century." Check out this outstanding source for Constitutional history background and research."
