CitationStyles.org is the home of the Citation Style Language (CSL), an open XML-based language to describe the formatting of citations and bibliographies.
Over the years, CSL has become the standard way to add citation support to software. We maintain a repository with over 7000 free CSL citation styles, many of which have been created by the user community. A wide range of commercial and open source software products use CSL, including ACS ChemWorx Desktop, BibSonomy, Bielefeld University Library’s Katalog.plus!, Cite This For Me, colwiz, CrossRef, digi-libris Reader, Docear, Drupal, Fidus Writer, Islandora, Jekyll, Logos, Mendeley, Multilingual Zotero, pandoc, Paperpile, Papers, Qiqqa, ReadCube, Refeus, Talis Aspire, WordPress (KCite and Zotpress plugins), and Zotero.
Look around to browse our CSL citation styles. Learn how to create and modify styles, how to support CSL in your own software, and how to participate in our open source project.
