David Livingstone's diaries of his exploration of inner Africa in the 19th century could do with a good going over to create something wonderful and slightly easier to read. They have a great amount of detail but it's an absolute slog to get through them.

For those who do not know:

David Livingstone (1813–1873) was a Scottish missionary, physician, and explorer known for his extensive travels across Africa in the 19th century. He is celebrated for his efforts to explore and map previously uncharted regions of the African continent, particularly his discovery of Victoria Falls, which he named after Queen Victoria. Livingstone sought to promote Christianity, commerce, and the abolition of the slave trade in Africa. His adventurous spirit and humanitarian goals made him a Victorian hero, though he faced significant challenges, including illness and isolation. His disappearance during one expedition led to the famous search and encounter with journalist Henry Morton Stanley, who greeted him with the iconic phrase, "Dr. Livingstone, I presume?"
