director of the Abraham Lincoln Presidential Library and Museum, said, "It is hard to imagine a more valuable or enduring contribution to Lincoln studies than a new, comprehensive, scholarly and widely accessible edition of his papers." Digital library April 19, 2018 marked the beginning of online publication of the Papers of Abraham Lincoln. It is composed of a Digital Edition and a Digital Archive. The Digital Edition includes transcriptions and images of documents written by or to Abraham Lincoln, presented in a searchable format. All documents in the Digital Edition are transcribed, single-proofed, and annotated; the transcriptions are orally double-proofed; and all annotation is fact-checked. The Digital Archive, released simultaneously with the Digital Edition, includes printed reports of speeches; routine government documents signed by Lincoln, such as military commissions; legislative documents from the Illinois General Assembly and Congress not authored by Abraham Lincoln; and other government documents (such as court-martial files) that were under Lincoln’s purview but for which we cannot positively prove direct interaction. The first online release of material included every known Lincoln document through 1842, when his career in the Illinois General Assembly ended. This amounted to 340 documents written by or to Lincoln and 4,839 documents that provide context on what issues Lincoln faced as a lawyer and legislator. The first document was a small workbook that Lincoln used as a schoolboy. Among the last was a letter in which Lincoln, who had recently broken up with Mary Todd, called himself "the most miserable man living."
