A biography is a set of facts or a report about someone's life, usually written by someone else.
Public records are documents or pieces of information and generally relate to the conduct of government, that is, the factual source.
The Almanac is usually an annual publication that gives the latest information on many topics, which is also a factual source.
What is not a factual source, it does not rely on concrete facts about a topic is a personal journal. It can be a casual record of ideas, experiences, thoughts, feelings, emotions, problems, self-assurances, which are recorded in some sort of diary, although it is much more personal than the diary.
