How it all began<\/span><\/h2>\n<\/div>\n<\/div>\n<\/div>\n
\n
\n
\n

In 2009, I faced the same problem that many students are familiar with: my university required a specific citation style \u2014 and that was nowhere to be found<\/strong>.<\/p>\n

So I took a look at the Citation Style Language<\/strong><\/a> (CSL)<\/strong> and thought it to myself in order to program my own style. First for myself, then for my fellow students. Then for a journal to which I submitted a paper from my doctoral thesis.<\/p>\n

Over the years, this has become a mission: I bridge the gap between the citation guidelines set by universities and journals and what is actually available in Zotero. Today, I am one of the top contributor of the CSL team<\/strong> and have created more than 1,000 styles for free<\/strong> and published them.<\/p>\n

Are you looking for a Zotero style developer<\/a>? With Citation Styler, I offer tried-and-tested, ready-to-use styles<\/strong> so that you can focus on your research, not on formatting.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
