I don't know about you, but watching the movie "Lincoln" sent me to the bookshelf and Internet to learn more about political wrangling over the adopition of the 13th Amendment.
The movie was a great political science lesson, but it was obvious that Steven Spielberg's epic was a big-screen CliffsNotes version of history. It was imposible to include all of the back stories involving Cabinet members and members of Congress. For example, I wanted to know much, much more about why legislators in my home state of Connecticut voted against the amendment.
For the complete version, there no better source than Doris Kearns Goodwin's "Team of Rivals," from which the movie was adapted, but the 900-plus pages may be daunting for some. Here's an alternative: The National Archives has produced "The Meaning and Making of Emancipation," an ebook that describes the years-long struggle through documents in the Archives' collection.
