CSE citation generator questions
Which CSE system does this page use?
It uses a CSE author-date style, which is common for science writing. Some courses may require a numeric CSE variant.
Can I cite biology journal articles?
Yes. DOI and title searches use CrossRef, and the result can be edited before copying.
Does CSE support websites and videos?
Yes. URL metadata extraction is used for web pages, and video entries can be completed manually when metadata is thin.
Why do I see a missing field warning?
The source may not expose all fields through a free metadata API. Add the missing information manually before use.
