On July 4, 1860, Americans at home and abroad sang, marched, recited the Declaration of Independence, and raised glasses to toast the eighty-fourth birthday of the United States of America—an unprecedented, if greatly flawed, democratic republic established by people determined to forge a future untainted by the tyrannies of the past. Yet only a few months after these grand celebrations, Southern states—whose economies rested heavily upon the backs of four million people held in slavery—began seceding from the Union. By February 1861, the American experiment in representative democracy trembled on the verge of failure.

Two weeks after the artillery barrages in Charleston Harbor ignited the Civil War, the Library of Congress celebrated its sixty-first birthday. Then located in the U.S. Capitol, the Library held seventy thousand volumes and a small collection of maps that members of Congress consulted as they addressed the increasingly complex issues confronting the troubled nation. Southern legislators who had withdrawn from Congress and returned to their states still had some 276 volumes charged out to them that historic April; and Commander in Chief Lincoln would soon be borrowing books from the Library’s collections as he schooled himself in military strategy during the first years of the war. In May 1861, President Lincoln appointed a political supporter, Indiana physician John G. Stephenson, as the fifth Librarian of Congress. This proved to be beneficial for many of the soldiers who garrisoned the nation’s capital, for, in addition to heading the small Library staff, Stephenson volunteered his medical services in some of Washington’s hospitals and makeshift infirmaries. In 1863, he served as a volunteer aide-de-camp during the battles of Chancellorsville and Gettysburg.

Stephenson and the assistant librarian, Ainsworth Rand Spofford, who became the sixth Librarian of Congress in 1864, also began acquiring material pertaining to the Civil War, a process that continues to the present day. Among the more than 145 million items that the Library now holds for Congress, the nation, and the world are well over a thousand discrete manuscript collections, including the papers of Abraham Lincoln, “Angel of the Battlefield” Clara Barton, abolitionist and former slave Frederick Douglass, and Confederate general Jubal A. Early, as well as letters and diaries of many less well-known soldiers and civilians on both sides.

Our Civil War collections also include military maps created by both Confederate and Union topographical engineers; photographs by Mathew Brady, George Barnard, Timothy O’Sullivan, and others; original drawings made by Alfred R. Waud and other Union special artist-correspondents and by soldier-artists such as William McIlvaine, James Fuller Queen, and Charles Wellington Reed; sheet music written and sung during the war; envelopes decorated with Union and Confederate political messages; law books and other administrative publications of the Confederate and United States; color and black-and-white lithographs depicting battles, leaders, and patriotic wartime themes; political cartoons, newspapers, and broadsides; dime novels, poetry, and memoirs published during the war; and thousands upon thousands of postwar memoirs and histories, including contemplations of the war and its reverberations published during the fiftieth, seventy-fifth, and one hundredth anniversaries of our nation’s most rending conflict.

Published as the sesquicentennial commemoration of the war begins, The Library of Congress Illustrated Timeline of the Civil War includes more than dozens of illustrations as well as a rich compendium of facts and quotations drawn from this unparalleled wealth of material. Starting with the journeys that presidents-elect Lincoln and Davis began on February 11, 1861, departing their homes to travel to their inaugurations, and concluding with a brief survey of postwar changes and challenges, this absorbing outline of four of the most difficult years in American history reflects the complexity, anguish, stubborn determination, and valor that characterized both sides of this bitter, fratricidal war. More than a history, the Illustrated Timeline is also an invitation to delve more deeply into Civil War history by visiting the Library—online at www.loc.gov, in person, and via the Library’s other print and electronic publications. To begin your investigation, see “Civil War Collections in the Library of Congress,” here.

Emerging from the war terribly wounded but still very much intact, with slavery finally and forever outlawed within its borders, the United States has gone on to celebrate 146 birthdays since 1865. Each year of the country’s existence brings stunning accomplishments and formidable challenges; each challenge underlines the importance of moving into the future armed with the best possible understanding of the past. In the Library of Congress, so often and aptly called the “Nation’s Memory,” history is alive and accessible in media from books to movies, from manuscripts to “tweets.” I hope you will accept this invitation to explore our collections. You will be amazed, moved, stimulated, and enlightened by what you will find.
