White paper

A white paper (sometimes referred to as a white book) is a 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 are a type of grey literature.
In government.
The term "white paper" originated with the British government, and many point to the Churchill White Paper of 1922 as the earliest well-known example under this name. Gertrude Bell, the British explorer and diplomat, was the first woman to author a White Paper. Her 149-page report was entitled "Review of the Civil Administration of Mesopotamia" and was presented to Parliament in 1920. In British government it is usually the less extensive version of the so-called "blue book", both terms being derived from the colour of the document's cover.
White papers are a "tool of participatory democracy ... not [an] unalterable policy commitment". "White papers have tried to perform the dual role of presenting firm government policies while at the same time inviting opinions upon them."
In Canada, a white paper is "a policy document, approved by Cabinet, tabled in the House of Commons and made available to the general public". The "provision of policy information through the use of white and green papers can help to create an awareness of policy issues among parliamentarians and the public and to encourage an exchange of information and analysis. They can also serve as educational techniques."
White papers are a way the government can present policy preferences before it introduces legislation. Publishing a white paper tests public opinion on controversial policy issues and helps the government gauge its probable impact.
By contrast, green papers, which are issued much more frequently, are more open-ended. Also known as "consultation documents", green papers may merely propose a strategy to implement in the details of other legislation, or they may set out proposals on which the government wishes to obtain public views and opinion.
Examples of governmental white papers include, in Australia, the White Paper on Full Employment and, in the United Kingdom, the White Paper of 1939 and the 1966 Defence White Paper.
In Israeli history, the White Paper of 1939 – marking a sharp turn against Zionism in British policy and at the time greeted with great anger by the Jewish Yishuv community in Mandatory Palestine – is remembered as ""The" White Paper" (in Hebrew Ha'Sefer Ha'Lavan  – literally "The White Book").
In business-to-business marketing.
Since the early 1990s, the terms "white paper" or "whitepaper" have been applied to documents used as marketing or sales tools in business. These white papers are long-form content designed to promote the products or services from a specific company. As a marketing tool, these papers use selected facts and logical arguments to build a case favorable to the company sponsoring the document.
B2B (business-to-business) white papers are often used to generate sales leads, establish thought leadership, make a business case, grow email lists, grow audiences, increase sales, or inform and persuade readers. The audiences for a B2B white paper can include prospective customers, channel partners, journalists, analysts, investors, or any other stakeholders.
White papers are considered to be a form of content marketing or inbound marketing; in other words, sponsored content available on the web with or without registration, intended to raise the visibility of the sponsor in search engine results and build web traffic. Many B2B white papers argue that one particular technology, product or methodology is superior to all others for solving a specific business problem. They may also present research findings, list a set of questions or tips about a certain business issue, or highlight a particular product or service from a vendor.
There are, essentially, three main types of commercial white papers:
While a numbered list may be combined with either other type, it is not workable to combine a backgrounder with a problem/solution white paper. While a backgrounder looks inward at the details of one particular product or service, a problem/solution looks outward at an industry-wide problem. This is rather like the difference between looking through a microscope and looking through a telescope.
Variants.
Several variations on the colour theme exist:
Two others are much less well established:
