Whitepaper
A white paper is an authoritative report or guide that informs readers concisely about a complex issue and presents the issuing body's philosophy on the matter. It is meant to help readers understand an issue, solve a problem, or make a decision.
The initial British term concerning a type of government-issued document has proliferated, taking a somewhat new meaning in business. In business, a white paper is closer to a form of marketing presentation, a tool meant to persuade customers and partners and promote a product or viewpoint, White papers may be considered grey literature.
Since the early 1990s, the term "white paper", or "whitepaper", has been applied to documents used as marketing or sales tools in business.
