Scholarpedia is an English-language wiki-based online encyclopedia with features commonly associated with open-access online academic journals, which aims to have quality content in science and medicine. Scholarpedia articles are written by invited or approved expert authors and are subject to peer review. Scholarpedia lists the real names and affiliations of all authors, curators and editors involved in an article: however, the peer review process (which can suggest changes or additions, and has to be satisfied before an article can appear) is anonymous. Scholarpedia articles are stored in an online repository, and can be cited as conventional journal articles (Scholarpedia has the ISSN number ). Scholarpedias citation system includes support for revision numbers. The project was created in February 2006 by Eugene M. Izhikevich, while he was a researcher at the Neurosciences Institute, San Diego, California. Izhikevich is also the encyclopedia's editor-in-chief. Scope Scholarpedia content is grouped into separate "encyclopedias". Currently seven of these are described as "focal areas": Astrophysics, Celestial mechanics, Computational neuroscience, Computational intelligence, Dynamical systems, Physics and Touch – but a further 12 include such diverse areas such as Play Science and Models of brain disorders. , Scholarpedia has 1,804 content pages and 18,149 registered users, as of November 2021, it has 1,812 peer-reviewed articles. Authorship To ensure that the articles are written by experts, authors of the various articles in Scholarpedia are either invited by the editor-in-chief or other curators, or selected by a public election. For example, Jimmy Wales and Larry Sanger were nominated for the article on Wikipedia. As of May 2009, the list of authors included four Fields Medalists and sixteen Nobel Prize winners. Registered users must provide their full real name, and a recognized affiliation to an academic institution. Only registered users can edit an article, and those edits are subject to approval by the curator of the article, who is typically the author. Curatorship is transferable. Users have a curator index attribute which is incremented or decremented by various activities and which affects the user's capabilities on the website. After October 20, 2011, anyone can propose an article for Scholarpedia, but articles must be sponsored by Editors or Curators before the article can be published. Copyright Articles are available online without charge for non-commercial use, but may not be copied in bulk. Authors are credited on the article page and in the suggested citation formats.
