Margin (typography) in the context of "Justification (typesetting)"

The National Geographic Society, headquartered in Washington, D.C., United States, is one of the largest nonprofit scientific and educational organizations in the world.

Founded in 1888, its interests include geography, archaeology, natural science, the promotion of environmental and historical conservation, and the study of world culture and history. The National Geographic Society's logo is a yellow portrait frame—rectangular in shape—which appears on the margins surrounding the front covers of its magazines and as its television channel logo. Through National Geographic Partners (a joint venture with The Walt Disney Company), the Society operates the magazine, TV channels, a website, worldwide events, and other media operations.

Marginalia (or apostils) are marks made in the margins of a book or other document. They may be scribbles, comments, glosses (annotations), critiques, doodles, drolleries, or illuminations.

Book design is the graphic art of determining the visual and physical characteristics of a book. The design process begins after an author and editor finalize the manuscript, at which point it is passed to the production stage. During production, graphic artists, art directors, or professionals in similar roles will work with printing press operators to decide on visual elements—including typography, margins, illustrations, and page layout—and physical features, such as trim size, type of paper, kind of printing, binding.

From the late Middle Ages to the 21st century, the basic structure and organization of Western books have remained largely unchanged. Front matter introduces readers to the book, offering practical information like the title, author and publisher details, and an overview of the content. It may also include editorial or authorial notes providing context. This is followed by the main content of the book, often broadly organized into chapters or sections. The book concludes with back matter, which may include bibliographies, appendices, indexes, glossaries, or errata.

In typography, a column is one or more vertical blocks of content positioned on a page, separated by gutters (vertical whitespace) or rules (thin lines, in this case vertical). Columns are most commonly used to break up large bodies of text that cannot fit in a single block of text on a page. Additionally, columns are used to improve page composition and readability. Newspapers very frequently use complex multi-column layouts to break up different stories and longer bodies of texts within a story. Column can also more generally refer to the vertical delineations created by a typographic grid system which type and image may be positioned. In page layout, the whitespace on the outside of the page (bounding the first and last columns) are known as margins; the gap between two facing pages is also considered a gutter, since there are columns on both sides. (Any gutter can also be referred to as a margin, but exterior and horizontal margins are not gutters.)

In some cases, column numbers are provided to improve specifying the in-source location in addition to or in absence of page numbers in serial publications, legal documents and patents. Historically, column designations were abbreviated "c" (singular) or "cc" (plural), i.e. "c130" or "cc130–136".

A drollery, often also called a grotesque, is a small decorative image in the margin of an illuminated manuscript, most popular from about 1250 through the 15th century, though found earlier and later. The most common types of drollery images appear as mixed creatures, either between different animals, or between animals and human beings, or even between animals and plants or inorganic things. Examples include cocks with human heads, dogs carrying human masks, archers winding out of a fish's mouth, bird-like dragons with an elephant's head on the back. Often they have a thematic connection with the subject of the text of the page, and larger miniatures, and they usually form part of a wider scheme of decorated margins, though some are effectively doodles added later. The word comes from the French drôlerie, meaning a joke.

One manuscript, The Croy Hours, has so many it has become known as The Book of Drolleries. Another manuscript that contains many drolleries is the English Luttrell Psalter, which has hybrid creatures and other monsters on a great deal of the pages. This comes from the East Anglian school of illumination, which was especially fond of adding drolleries. The Taymouth Hours, Gorleston Psalter, and Smithfield Decretals are other examples; all four are 14th-century and now in the British Library. In the Taymouth Hours the images are inside the main frame given each page, and so are strictly bas de page images rather than being "marginal". The images mix sacred subjects relevant to the text with secular ones that are not. Such images are the most plentiful sources of contemporary illustrations of ordinary life in the period, and many are often seen reproduced in modern books.
