Over the past decade I've noticed on HN the following order of frequency in choice of words, most common to least:

1. Citation

2. Source

3. Reference

Long ago in a career based on original research, I/we ONLY used "reference."

While it is definitely over a decade at this point (over two in fact), some of this likely comes from the term [citation needed], that originated on Wikipedia, as a cynical backhanded response to unsourced claims. It has become a catch-all. Language and how it evolves is a pretty interesting subject.
