But creating a style that truly complies with guidelines \u2013 covering all source types, special cases and language variants \u2013 is not a simple copy-and-paste job. It requires specialist expertise. And that is precisely what I have been passionate about since 2009.<\/p>\n<\/div>\n<\/div><div class=\"bde-column-16609-10 bde-column\">\n  \n  \n\t\n\n\n\n<div class=\"bde-div-16609-5 bde-div\">\n  \n  \n\t\n\n\n\n\n<\/div><div class=\"bde-div-16609-8 bde-div\">\n  \n  \n\t\n\n\n\n<div class=\"bde-text-16609-6 bde-text\">\nCSL maintainer\n<\/div><div class=\"bde-text-16609-7 bde-text\">\nOfficial contributor to the global CSL repository, with hundreds of published styles.\n<\/div>\n<\/div>\n<\/div><\/div><\/div>\n<\/section><section class=\"bde-section-16609-16 bde-section\">\n  \n  \n\t\n\n\n\n<div class=\"section-container\"><h2 class=\"bde-heading-16609-13 bde-heading\">\nWhy CSL style development is a highly specialised skill\n<\/h2><div class=\"bde-div-16609-15 bde-div\">\n  \n  \n\t\n\n\n\n<div class=\"bde-rich-text-16609-14 bde-rich-text breakdance-rich-text-styles\">\n<p>The Citation Style Language is an XML-based format with an extensive <span style=\"color: rgb(50, 102, 173);\">specifications<\/span>. A typical academic citation style must correctly handle dozens of different scenarios \u2013 from edited volumes to journal articles with a DOI, and from draft legislation to websites without an author. The difficulty lies not in any single case, but in the interplay between them: every rule must be consistent with every other.<\/p><p>Furthermore, it is essential to be familiar and understand how CSL and Zotero integrate.
