What-is-What does not accept anonymous contributions and all contributors to an article are listed in the recommended citation format. Most articles have a single author. Recognising the difficulty in obtaining primary sources in the technology sector, especially in regards to open source software, What-is-What sources all information from official documentation including software manuals, press releases, peer-reviewed scientific journals, public statements by software authors, other such reliable sources. What-is-What is often cited on community-compiled references such as internet forums, Wikipedia, and IRC.
