This article is about a recovered field diary from the 19th century. The diary belonged to David Livingstone, a Scottish missionary and explorer. In most cases, the ink is very faded or masked by newspaper ink (since at some point during his exploration, Livingstone ran out of paper, but instead used a newspaper to write on). However, by using light-emitting diodes and a very high-resolution digital camera, researchers were able to figure out what was written in Livingstone's diary and it is now being published for the first time.
