Information:  - Wikibooks ( previously called Wikimedia Free Textbook Project and Wikimedia - Textbooks ) is a wiki based Wikimedia project hosted by the Wikimedia Foundation for the creation of free content textbooks and annotated texts that anyone can edit . In September 2015 , Compete.com estimates that Wikibooks had 2,102,708 unique visitors .  - A content management system (CMS) is a computer application that supports the creation and modification of digital content. It is often used to support multiple users working in a collaborative environment.   - The Wikimedia movement is the global community of contributors to Wikimedia projects. The movement was created around Wikipedia, and has since expanded to many other projects, including the Wikipedia community with around 70,000 volunteers for other Wikimedia projects such as Wikidata and Wikimedia Commons, and volunteer software developers contributing to MediaWiki. These volunteers are supported by numerous organizations around the world, including the Wikimedia Foundation, related chapters, thematic organizations, and user groups.  - A Wikimedia project is a wiki-based community project run by the Wikimedia Foundation, a nonprofit organization founded in San Francisco, California in 2003. The Foundation operates many free software and free content projects, listed below, which are developed by volunteers of the Wikimedia movement.  - Free software, freedom-respecting software, or software libre is computer software distributed under terms that allow the software users to run the software for any purpose as well as to study, change, and distribute the software and any adapted versions. Free software is a matter of liberty, not price: users, individually or collectively, are free to do what they want with it, including the freedom to redistribute the software free of charge, or to sell it, or charge for related services such as support or warranty for profit.  - A wiki is a website that provides collaborative modification of its content and structure directly from the web browser. In a typical wiki, text is written using a simplified markup language (known as "wiki markup") and often edited with the help of a rich-text editor. A wiki is run using wiki software, otherwise known as a wiki engine. There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems. Some wiki engines are open source, whereas others are proprietary. Some permit control over different functions (levels of access); for example, editing rights may permit changing, adding or removing material. Others may permit access without enforcing access control. Other rules may also be imposed to organize content. A wiki engine is a type of content management system, but it differs from most other such systems, including blog software, in that the content is created without any defined owner or leader, and wikis have little implicit structure, allowing structure to emerge according to the needs of the users.  - Wiki software (also known as a wiki engine or wiki application) is collaborative software that runs a wiki, which allows users to create and collaboratively edit "pages" or entries via a web browser. A wiki system is usually a web application that runs on one or more web servers. The content, including all current and previous revisions, is usually stored in either a file system or a database. Wikis are a type of web content management system, and the most commonly supported off-the-shelf software that web hosting facilities offer. There are currently dozens of actively maintained wiki engines, in a variety of programming languages, including both open source and proprietary applications. These vary widely in their platform support, their support for natural language characters and conventions, and in their assumptions about technical versus social control of editing.

Information:  - High Inergy was an American R&B and soul girl group who found fame on Motown Records in the late 1970s. They are best known for their hit, "You Can't Turn Me Off (In the Middle of Turning Me On)".  - Pop music is a genre of popular music that originated in its modern form in the Western world as a softer alternative to rock and roll. The terms "popular music" and "pop music" are often used interchangeably, although the former describes all music that is popular and includes many styles. "Pop" and "rock" were synonymous terms until the late 1960s, when they were increasingly used in opposition from each other.  - A girl group is a music act featuring several female singers who generally harmonize together. The term "girl group" is also used in a narrower sense in the United States of America to denote the wave of American female pop music singing groups, many of whom were influenced by doo-wop, and which flourished in the late 1950s and early 1960s between the decline of early rock and roll and start of the British Invasion.  - `` You Ca n't Turn Me Off ( In The Middle Of Turning Me On ) '' is a 1977 single by girl group High Inergy . It was the first single off their debut album , Turnin ' On . The song reached # 2 on the Billboard Black Singles chart , and # 12 on the Pop Singles chart in 1978 . The song was written by Pam Sawyer and Marilyn McLeod . It was produced by Kent Washburn and arranged by Sylvester Rivers . The flipside , `` Save It for a Rainy Day '' was co-written by James Ingram .  - The British Invasion was a phenomenon that occurred in the mid-1960s when rock and pop music acts from the United Kingdom, as well as other aspects of British culture, became popular in the United States, and significant to the rising "counterculture" on both sides of the Atlantic. Pop and rock groups such as the Beatles, the Dave Clark Five, the Kinks, the Rolling Stones, Herman's Hermits, and the Animals were at the forefront of the invasion.  - Doo-wop is a genre of music that was developed in African-Americans communities of New York City, Philadelphia, Chicago, Baltimore, Newark, Pittsburgh, Cincinnati, Detroit, Washington, D.C. and Los Angeles in the 1940s, achieving mainstream popularity in the 1950s and early 1960s. Built upon vocal harmony, doo-wop was one of the most mainstream, pop-oriented R&B styles of the time. Singer Bill Kenny (19141978) is often called the "Godfather of Doo-wop" for his introducing the "top and bottom" format which featured a high tenor singing the lead and a bass singer reciting the lyrics in the middle of the song. Doo-wop features vocal group harmony, nonsense syllables, a simple beat, sometimes little or no instrumentation, and simple music and lyrics.
