A diary is a written or audiovisual memorable record, with discrete entries arranged by date reporting on what has happened over the course of a day or other period.
Today the term is generally employed for personal diaries, normally intended to remain private or to have a limited circulation amongst friends or relatives.
In recent years, however, there is internal evidence in some diaries (e.g. those of Ned Rorem, Alan Clark, Tony Benn or Simon Gray) that they are written with eventual publication in mind, with the intention of self-vindication (pre- or posthumous), or simply for profit.
Pillowbooks of Japanese court ladies and Asian travel journals offer some aspects of this genre of writing, although they rarely consist exclusively of diurnal records.
[4] The precursors of the diary in the modern sense include daily notes of medieval mystics, concerned mostly with inward emotions and outward events perceived as spiritually important (e.g. Elizabeth of Schönau, Agnes Blannbekin, and perhaps also, in the lost vernacular account of her visions, Beatrice of Nazareth).
From the Renaissance on, some individuals wanted not only to record events, as in medieval chronicles and itineraries, but also to put down their own opinions and express their hopes and fears, without any intention to publish these notes.
One of the early preserved examples is the anonymous Journal d'un bourgeois de Paris covering the years 1405–1449, giving subjective commentaries on current events.
Famous 14th to 16th century Renaissance examples, which appeared much later as books, were the diaries by the Florentines Buonaccorso Pitti and Gregorio Dati and the Venetian Marino Sanuto the Younger.
Among important U.S. Civil War diaries are those of George Templeton Strong, a New York City lawyer, and Mary Chesnut, the wife of a Confederate officer.
The diary of Jemima Condict, living in the area of what is now West Orange, New Jersey, includes local observations of the American Revolutionary War.
Friedrich Kellner, a court official in Nazi Germany, thought of his diary as a weapon for any future fight against tyrants and terrorism, and named it 'Mein Widerstand', My Opposition.
Victor Klemperer was similarly concerned with recording for the future the tyrannies and hypocrisies of Nazi Germany and of its East German successor state in his diaries.
[citation needed] As internet access became commonly available, many people adopted it as another medium in which to chronicle their lives with the added dimension of an audience.
Proponents have cited numerous reasons for journaling using digital applications, including ease and speed of typing, mobile portability, and search capabilities.
[13] Digital diaries are also tailored towards shorter-form, in-the-moment writing, similar to user engagement with social media services such as Facebook, Twitter and Instagram.
A personal organizer is a form of diary to list actions and tasks for the day, which are recorded in a log, often using symbols to differentiate and categorize items.
