Addy Studies Freedom seems to take place between Happy Birthday Addy and Addy Saves the Day, as it takes place shortly after the war has ended and before Poppa has gone south on his initial search for Esther and Sam. This book is about the tension and internal struggle in the contradiction Addy sees between what she expected freedom would be like, and the racism she and her family are still experiencing from whites after being freed. Her teacher, Miss Dunn has asked the class to write a short essay about Why Their Hearts are Glad that Their Country is Free, but Addy starts pondering that there is a different freedom for blacks and whites, and yearns for President Lincoln to create what she terms 'one freedom' for everybody.
It's then that Addy hears about Lincoln's assassination, and we get a very detailed description of the celebrations of the end of the war abruptly ceasing and people weeping openly in the streets, and how Lincoln was viewed as a martyr akin to christ or moses, dying to bring salvation and freedom to his people. His funerary coach riding through Pennsylvania, and waiting in line to view his body and coffin. I remember learning at one point that his body's embalming was one of the early examples of the advancements in the undertaker industry when it comes to preserving bodies for viewings, as Lincoln's body needed to be preserved for weeks for viewings across the country.
A few different opinions about Lincoln are tossed out in this book from the adult characters, but Lincoln's actual political stances are kept simplistic for the young audience. Although it's known that he waffled a few times, he ultimately did complete the abolition of slavery and wrote about how feelings that despite his belief that the races were not equal, his conscience tormented him just the same, and is what ultimately drove him to sign the emancipation proclamation and see the war through. He deserves credit for having the guts to do that. There's a reason he's so widely beloved.
By the end of the short-story, her father tells her that freedom isn't a process that happens overnight, and Addy accepts that they've known some kind white people in their time in the North, and that progress towards true freedom and equality of the races is being made, step by step... and 160 years later, we're still taking step after slow weary step.
As for the 'Looking Back' section, I forgot that there were photographs of Lincoln's hearse. Like, we have black and white still photos of people from this time-period, but I haven't seen very many city-wide shots or views of crowds, as cameras still worked best on still scenes and had a long exposure time. It was cool to see such detailed drawings of the hurse and the carriage.
