The "leather book" originated from a specific report of a government department on a specific issue. Usually this kind of report is printed without any modification, and the cover is black and white, so it is called "white paper". For example, the Statement on US-China Relations issued by the United States in August 1949 is a white paper. The cover is blue, called blue book; The red one is called the little red book; Use yellow, called yellow book; Use green, called green book, etc.
White paper and blue book are the most used countries, especially the white paper has become an internationally recognized official document. However, a country can use multiple document cover colors. For example, Japan's annual defense report uses a white paper, called the defense white paper, while its annual diplomatic report uses a blue book, called the diplomatic blue book.

Since 1990s, "White Paper" has been used as a marketing and sales tool in Chinese mainland. But in most democratic countries, because the government is responsible to citizens and taxpayers, the white paper still refers to the public policy documents of the government or public service departments.
The meaning of extending the white paper to "Marketing and Sales Tools Documentation" is limited to Chinese mainland enterprises. In the general western, Taiwan Province, Japanese and Asia-Pacific enterprises, most of these marketing documents are called sales tools or sales guides.
Countries around the world generally pay more attention to national defense white papers or similar forms of government statements, explaining national defense policies at home and abroad, in order to further clarify national defense or military trends, increase military transparency, and strive to establish their own good international image and satisfy the domestic people's right to know.
