The charismatic Theodore Roosevelt, who served as the 26th president of the United States from 1901-1909, was an influential public servant and reformer, a naturalist, and a prolific writer. The Library of Congress has long held the largest archival collection of Roosevelt's personal papers, and now this massive trove of approximately 276,000 documents (about 461,000 images) has been digitized. This vast collection includes letters that Roosevelt sent and received; speeches and executive orders in multiple drafts; Roosevelt's personal diaries from 1878-1884; contemporaneous newspaper and magazine clippings; and many papers documenting activities in the White House, such as desk diaries, reception books, and press releases. Examples of notable documents include a personal diary entry from February 14, 1884, consisting only of the sentence, "The light has gone out of my life," written when Roosevelt's mother and wife died on the same day. Another letter, from 1907, written to his son Archibald humorously describes an incident involving Archibald's younger brother Quentin, three pet snakes, and four congressmen waiting for an appointment. Historians, scholars, and general audiences alike will find much to interest them in this important collection.
