Generally, Source are written materials or objects that are used to gather and record information. The type of source material that a writer uses depends on the purpose for which the source is intended. A writer may use both primary and secondary sources.
A primary source is a document written directly by the subject of the writing. A secondary source is a document that is based on the study of another document. A secondary source is often used to give an explanation of a primary source.
The main purpose of a source is to provide timely information on a certain topic. This includes giving an idea of how things happen and how people got to the point they are at. It is also used to support an argument.
A source can be a person, a place, a document, a video, or a piece of art. It can be a spoken or written statement. It can also be a graphic representation.
A primary source is directly related to the era, the subject, or the person who created the document. It can be a document written by a scientist or an author who is working on a specific topic. A secondary source is a document written by a person who knows something about the era, the subject, or the document. It can be a book, a newspaper report, or a document written in a scientific journal.
A tertiary source is a source that provides the reader with additional information. It can include encyclopedias, textbooks, fact books, manuals, and reference materials.
