A brochure is an informative paper document (often also used for advertising) that can be folded into a template, pamphlet or leaflet. A brochure can also be a set of related unfolded papers put into a pocket folder or packet. Brochures are promotional documents, primarily used to introduce a company, organization, products or services and inform prospective customers or members of the public of the benefits.

Brochures are distributed in many different ways: as newspaper inserts, handed out personally, by mail or placed in brochure racks in high traffic locations especially in tourist precincts.
The most common types of single-sheet brochures are the bi-fold (a single sheet printed on both sides and folded into halves) and the tri-fold (the same, but folded into thirds). A bi-fold brochure results in four panels (two panels on each side), while a tri-fold results in six panels (three panels on each side).

A newsletter is a printed report containing news (information) of the activities of a business (legal name; subscription business model) or an organization (institutions, societies, associations) that is sent by mail regularly to all its members, customers, employees or people, who are interested in it. Newsletters generally contain one main topic of interest to its recipients. A newsletter may be considered grey literature. E-newsletters are delivered electronically via e-mail and can be viewed as spamming if sent unsolicited.
