Non-fiction (or nonfiction) is any document or media content that attempts, in good faith, to convey information only about the real world, rather than being grounded in imagination. Non-fiction typically aims to present topics objectively based on historical, scientific, and empirical information. However, some non-fiction ranges into more subjective territory, including sincerely held opinions on real-world topics.

Often referring specifically to prose writing, non-fiction is one of the two fundamental approaches to story and storytelling, in contrast to narrative fiction, which is largely populated by imaginary characters and events. Non-fiction writers can show the reasons and consequences of events, they can compare, contrast, classify, categorise and summarise information, put the facts in a logical or chronological order, infer and reach conclusions about facts, etc. They can use graphic, structural and printed appearance features such as pictures, graphs or charts, diagrams, flowcharts, summaries, glossaries, sidebars, timelines, table of contents, headings, subheadings, bolded or italicised words, footnotes, maps, indices, labels, captions, etc. to help readers find information.

Information is an abstract concept that refers to something which has the power to inform. At the most fundamental level, it pertains to the interpretation (perhaps formally) of that which may be sensed, or their abstractions. Any natural process that is not completely random and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analogue signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form. Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation.

The concept of information is relevant or connected to various concepts, including constraint, communication, control, data, form, education, knowledge, meaning, understanding, mental stimuli, pattern, perception, proposition, representation, and entropy.

A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms a sign of disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs (notices, road signs, etc., collectively known as signage) generally inform or instruct using written text, symbols, pictures or a combination of these.

The philosophical study of signs and symbols is called semiotics; this includes the study of semiosis, which is the way in which signs (in the semiotic sense) operate.

An art exhibition is traditionally the space in which art objects (in the most general sense) meet an audience. The exhibit is universally understood to be for some temporary period unless, as is occasionally true, it is stated to be a "permanent exhibition". In American English, they may be called "exhibit", "exposition" (the French word) or "show". In UK English, they are always called "exhibitions" or "shows", and an individual item in the show is an "exhibit".

Such expositions may present pictures, drawings, video, sound, installation, performance, interactive art, new media art or sculptures by individual artists, groups of artists or collections of a specific form of art.

A picture frame is a protective and decorative edging for a picture, such as a painting or photograph. It makes displaying the work safer and easier and both sets the picture apart from its surroundings and aesthetically integrates it with them.

A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper.Watermarks have been used on postage stamps, currency, and other government documents to discourage counterfeiting. There are two main ways of producing watermarks in paper; the dandy roll process, and the more complex cylinder mould process.

Watermarks vary greatly in their visibility; while some are obvious on casual inspection, others require some study to pick out. Various aids have been developed, such as watermark fluid that wets the paper without damaging it. A watermark is very useful in the examination of paper because it can be used for dating documents and artworks, identifying sizes, mill trademarks and locations, and determining the quality of a sheet of paper. The word is also used for digital practices that share similarities with physical watermarks. In one case, overprint on computer-printed output may be used to identify output from an unlicensed trial version of a program. In another instance, identifying codes can be encoded as a digital watermark for a music, video, picture, or other file. Or an artist adding their identifying digital Signature, graphic, logo in their digital artworks as an identifier or anti-counterfeit measure.
