It is useful at times to read published diaries and get a feel for why and how others have taken up the pen. Some have written with the expectation of readers, others not so much. The common denominator is that these are diaries which are in the public domain and available to read for free online. Enjoy.

Robert Scott (1868-1912) – Captain Robert Scott let British Antarctic expeditions -the Discovery (1901–1904) and Terra Nova (1910–1913). The Terra Nova Antarctic Diaries are available at the British Library to read online. The diaries, “document all aspects of the expedition, including: · the voyage · establishment of the winter base · scientific work · sledging expeditions,” according to the British Library. Interestingly, Scott “wrote most of his entries sequentially on one side of the page, leaving the other side blank,” says the British Library. “In some instances he later used the blank pages to write further entries, reversing the diary and writing from the back of the volume forwards. These entries appear upside down in the original volumes,” they continue. The website allows you to rotate the diary so that one does not need to read it upside down; they also have a transcription in san serif typeface for easier reading.
