This bibliography of Abraham Lincoln is a comprehensive list of written and published works about or by Abraham Lincoln, 16th President of the United States.
 In terms of primary sources containing Lincoln's letters and writings, scholars rely on "The Collected Works of Abraham Lincoln", edited by Roy Basler, and others.
 It only includes writings by Lincoln, and omits incoming correspondence.
 In the six decades since Basler completed his work, some new documents written by Lincoln have been discovered.
 Currently, a project is underway at the Papers of Abraham Lincoln to provide "a freely accessible comprehensive electronic edition of documents written by and to Abraham Lincoln".
 The Papers of Abraham Lincoln completed Series I of their project "The Law Practice of Abraham Lincoln" in 2000.
 They electronically launched "The Law Practice of Abraham Lincoln, Second Edition" in 2009, and published a selective print edition of this series.
 At present they are engaged in locating, digitizing, and transcribing documents for Series II (non-legal, pre-presidential materials) and Series III (presidential materials).
The sexuality of Abraham Lincoln (1809–1865), the 16th President of the United States, has been a topic of debate among some scholars.
 Lincoln was married to Mary Todd from November 4, 1842, until his death on April 15, 1865, and fathered four children with her.
 The issue came to greater attention due to a 2005 book "The Intimate World of Abraham Lincoln" by psychologist C. A. Tripp, which described Lincoln as allegedly having a detached relationship with women, in contrast with a close male friend he allegedly shared a bed with.
 According to the book "Lincoln the Unknown", Lincoln chose to spend several months of the year practicing law on a circuit that kept him living separately from his wife.
 In 1928, a prominent writer had pointed to a close male friend of the young Lincoln as a possible lover that was denounced as absurd at the time.
Lincoln the Unknown is a biography of Abraham Lincoln, written in 1932 by Dale Carnegie.
 It is published by Dale Carnegie and Associates, and given out as a prize in the Dale Carnegie Course.
Abe is a musical in two acts based on the life of President Abraham Lincoln with book & lyrics by Lee Goldsmith, music by Roger Anderson and orchestration by Greg Anthony.
 The musical covers the life of Abraham Lincoln from his earliest attempts at self-improvement through the 1860 election which made him the 16th president of an already fracturing United States.
 Also explored is Lincoln's youth as a flatboat pilot on the Mississippi, his early love for Ann Rutledge, his troubled marriage to the difficult and mentally fragile Mary Todd, and his attempt to be a good father to his sons.
Abraham Lincoln, also released under the title D. W. Griffith's "Abraham Lincoln", is a 1930 Pre-Code biographical film about American president Abraham Lincoln directed by D. W. Griffith.
 It stars Walter Huston as Lincoln and Una Merkel, in her second speaking role, as Ann Rutledge.
 Her first speaking role was in a short film, "Love's Old Sweet Song" (1923) filmed in the Phonofilm sound-on-film process.
 The script was co-written by Stephen Vincent Benét and Gerrit Lloyd, author of the Civil War prose poem "John Brown's Body".
 This was the first of only two sound films made by Griffith.
