What institution holds the only known manuscript copy of Alice's Adventures Under Ground?

The British Library holds the only known manuscript copy of Alice’s Adventures Under Ground.

Lewis Carroll, whose real name was Charles Lutwidge Dodgson, originally wrote and illustrated this manuscript for Alice Liddell. He presented it to her in 1864 as a Christmas gift titled Alice’s Adventures Under Ground. The handwritten version is an early form of the story later expanded and published as Alice’s Adventures in Wonderland.

The manuscript is much shorter than the printed novel and contains Carroll’s own illustrations. It is divided into four untitled chapters, while the 1865 published book has twelve titled chapters and includes episodes that do not appear in the manuscript, such as the Mad Hatter’s tea party.

Alice Liddell’s copy was sold at Sotheby’s in 1928. After passing through American ownership, it was presented to Britain in 1948 and entered the British Library’s collections. “Manuscript copy” means Carroll’s original handwritten and illustrated book, not one of the later printed facsimiles.
