We have been featuring a good bit of content relating to the 150th anniversary of the Emancipation Proclamation this year. That document, along with the Gettysburg Address, is often seen as the pinnacle of President Lincoln's political output. If you're interested a broader look at his political and legal career, though, there is an online resource you should check out.
The Papers of Abraham Lincoln is a cooperative repository curated by the Illinois Historic Preservation Agency and the Abraham Lincoln Presidential Library and Museum. They have collected documents from hundreds of participating institutions across the country into a single portal. In addition to the expected speeches, correspondence, and printed materials, they have also sought out Lincoln's voting records, financial documents, autographs, and handwritten inscriptions in books.
They have used this wealth of information to create The Lincoln Log, a searchable timeline of Lincoln's life. You can see what Lincoln was up to on a given date, search by keywords, or browse an entire year.
The item that caught my eye was a recently discovered letter of introduction for Emilie Jane Merriman, a correspondent for the New York Times, that is held by the Bibliothèque de Genève in Switzerland. Such a document would be unremarkable if not for the fact that it is signed by her minister, Henry Ward Beecher, and has a postscript note from Abraham Lincoln. Merriman's story is quite interesting. If you have a few minutes, go read it.
