KWIC is an acronym for Key Word In Context, the most common format for concordance lines. The term KWIC was first coined by Hans Peter Luhn. The system was based on a concept called keyword in titles which was first proposed for Manchester libraries in 1864 by Andrea Crestadoro.
A KWIC index is formed by sorting and aligning the words within an article title to allow each word (except the stop words) in titles to be searchable alphabetically in the index. It was a useful indexing method for technical manuals before computerized full text search became common.
For example, the title statement of this article and the Wikipedia slogan would appear as follows in a KWIC index. A KWIC index usually uses a wide layout to allow the display of maximum 'in context' information (not shown in the following example).

The term permuted index is another name for a KWIC index, referring to the fact that it indexes all cyclic permutations of the headings. Books composed of many short sections with their own descriptive headings, most notably collections of manual pages, often ended with a permuted index section, allowing the reader to easily find a section by any word from its heading. This practice is no longer common.

Famous quotes containing the words key, word and/or context:
“Every revolution was first a thought in one man’s mind, and when the same thought occurs in another man, it is the key to that era.”
—Ralph Waldo Emerson (1803–1882)
“All roads are blocked to a philosophy which reduces everything to the word “no.” To “no” there is only one answer and that is “yes.” Nihilism has no substance. There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing. Man lives more by affirmation than by bread.”
—Victor Hugo (1802–1885)
“The hippie is the scion of surplus value. The dropout can only claim sanctity in a society which offers something to be dropped out of—career, ambition, conspicuous consumption. The effects of hippie sanctimony can only be felt in the context of others who plunder his lifestyle for what they find good or profitable, a process known as rip-off by the hippie, who will not see how savagely he has pillaged intricate and demanding civilizations for his own parodic lifestyle.”
—Germaine Greer (b. 1939)
