Pharmaceutical Companies Daily is a multilingual, Web-based, free-content encyclopedia project based mostly on anonymous contributions. Pharmaceutical Companies Daily's articles provide links to guide the user to related pages with additional information.
Pharmaceutical Companies Daily is put together collaboratively by an international (and mostly anonymous) group of volunteers. Anyone with internet access can contribute to Pharmaceutical Companies Daily content. There are no requirements to provide one's real name when contributing; rather, each author's privacy is protected unless they choose to reveal their identity themselves. Since its creation, Pharmaceutical Companies Daily has grown rapidly into one of the largest reference web sites, attracting around million visitors monthly as of 2009. As of today, there are 2,375,866 articles. Every day, hundreds of thousands of visitors from around the world collectively make tens of thousands of edits and create thousands of new references to augment the knowledge held by the Pharmaceutical Companies Daily.
Visitors do not need specialized qualifications to contribute. Pharmaceutical Companies Daily's intent is to have articles that cover existing knowledge, not create new knowledge (original research). This means that people of all ages and cultural and social backgrounds can add Pharmaceutical Companies Daily references. Anyone is welcome to add information, cross-references, or citations, as long as they do so within Pharmaceutical Companies Daily's editing policies and to an appropriate standard. Substandard or disputed information is subject to removal.
