Page (paper)

A page is one side of a leaf (a sheet or half-sheet) of paper, parchment or other material (or electronic media) in a book, magazine, newspaper, or other collection of sheets, on which text or illustrations can be printed, written or drawn, to create documents. It can be used as a measure of communicating general quantity of information ("That topic covers twelve pages") or more specific quantity ("there are 535 words in a standard page in twelve point font type").

Etymology
The word "page" comes from the Latin term pagina, which means, "a written page, leaf, sheet", which in turn comes from an earlier meaning "to create a row of vines that form a rectangle". The Latin word pagina derives from the verb pangere, which means to stake out boundaries when planting vineyards.

The page in library science
In library science, the number of pages in a book forms part of its physical description, coded in subfield $300a in MARC 21 and in subfield $215a in UNIMARC. This description consists of the number of pages (or a list of such numberings separated by commas, if the book contains separately-numbered sections), followed by the abbreviation "p." for "page(s)". The number of pages is written in the same style (Arabic or Roman numerals, uppercase or lowercase, etc.) as the numbering in each section. Unnumbered pages are not described.

For example,
 * XI, 2050 p.

describes a book with two sections, where section one contains 11 pages numbered using uppercase Roman numerals, and section two contains 2050 pages numbered using Arabic numerals; the total number of pages is thus 2061 pages, plus any unnumbered pages.

If the book contains too many separately-numbered sections, too many unnumbered pages, or only unnumbered pages, the librarian may choose to describe the book as just "1 v." (one volume) when doing original cataloguing.
