Diary
a daily record of events or observations made by an individual.
Diaries have often furnished the historian with invaluable material, supplying the absence of public records, and furnishing minute and intimate details of manners and of motives that do far more to help us to understand the past than more formal records. Such documents as Robert Baillie's "Journals," the "Diaries" of Pepys and Evelyn, and the "Journals" of Greville are among the most valuable sources of real history.
