One-click automation
Open the Publication → References tab, choose a style, and select Process & Format.
Professional citations without manual cleanup
Incomplete references, missing DOIs, inconsistent styles, and messy punctuation delay publication and undermine a journal’s professional image. Citation Styler brings Crossref and Crosscite enrichment directly into the OJS publication workflow, transforming raw references into DOI-enriched, consistently formatted citation lists in seconds.
Key features
Six citation styles
APA 7th, Chicago Author-Date, IEEE, MLA, Harvard, and Vancouver are available from a simple dropdown.
Smart enrichment & fallback
Crossref queries restore missing authors, years, publishers, and DOI links; fallback handling keeps data safe when an API is unavailable.
Intelligent sorting
Author-Date styles are alphabetized, while numbered styles preserve cited order and add sequential numbering.
Advanced cleanup
The plugin removes unwanted HTML, fixes duplicate punctuation and spacing, and normalizes all-caps author names.
Cyrillic & Latin aware
PHP Collator correctly sorts Č, Ć, Đ, Š, Ž and places Cyrillic references after Latin ones.
How it works
Select a submission, open References, choose a citation style, and click Process & Format. In under five seconds, the plugin cleans the text, obtains Crossref metadata, appends DOI links, formats and sorts citations, then saves the result back to OJS.
