Citation styles are the backbone of Zotero for any scientific work. They ensure consistency and accuracy in the citation of sources and help researchers to present their work clearly and precisely. But what do you do if the desired citation style is not available for your needs? This is where CSL comes in - the Citation Style Language.

What is CSL?

CSL is a special programming language that is used to define citation styles. CSL is an open-source project that volunteers like me maintain. With CSL, citation styles can be used in various reference management programmes such as Zotero or Mendeley. It makes it possible to customise the appearance of the desired citation style to match the requirements exactly.

Why is the customisation of citation styles important?

Standard citation styles are sometimes not able to fulfil the specific requirements of a scientific paper. Perhaps you need special formatting for certain publications or need to fulfill specific internal guidelines. The customisation of citation styles with CSL offers the flexibilityto satisfy this request to perfectly match your references. zu gewährleisten.

How does the editing of citation styles with CSL work?

To modify from citation style with CSL you will need some basic knowledge of programming and the CSL syntax (a type of XML that is quite simple). A style editor is built into Zotero itself (Tools > Developer > Style Editor) and you can select and customise a citation style directly there.
