Contributions published in the journal cover a vast variety of topics from the fields of linguistics, literature, anthropology, and history. While most contributions are in Slovenian or other Slavic languages, articles in English, Hungarian, and German are also welcome. The journal's website features an archive of past issues published under the Open Access licence. Slavia Centralis encourages contributions treating the Slavic languages and literatures holistically, transcending borders and national canons, as well as exploring connections between Slavic and non-Slavic.
In 2009 Nada Šabec's "Sloglish or the Mixing/Switching of Slovene and English in Slovene Blogs" was published as a seminal example of sociolinguistic and cultural aspects of using a language in the Internet environment.
