How does CitApp generate Proceedings of the National Academy of Sciences of the United States of America references?
CitApp renders Proceedings of the National Academy of Sciences of the United States of America using the same open-source engine (citeproc) that powers Zotero and Mendeley, from the official CSL style file, so the output matches the guide by construction — no AI in the loop, and the same source always produces the same reference.
Does Proceedings of the National Academy of Sciences of the United States of America work in Swedish?
Yes. Set the project language to Swedish and dates and terms follow, so an undated source renders as u.å. instead of n.d.
Prefer a built-in style?
