Citing a resource is when you publicly acknowledge it.
In text, you put a label, like [3], or (Weeks2007),
that corresponds to an entry in your references.
The reference section then includes a lot more information, namely where other
people can find it: the author's full name, the title of his/her paper,
the journal that published it, the publisher, the year, the pages, etc.
Typically, you see this in academic papers, but other places such as
Wikipedia pages often include citations and a reference section.
How do you cite software? I propose this bibtex entry for calq:
@misc{calq,
title = {Calq},
author = {Michael Weeks},
organization = {Digital Wave Systems Lab},
address = {Atlanta, Georgia, USA},
year = {2007--2019},
note = {version 4.2},
url = {http://hallertau.cs.gsu.edu/calq_latest},
}
If you use bibtex, just copy that and paste it in your references.
If you don't use bibtex, you can copy and paste this instead:
Michael Weeks, "Calq (software)", version 4.2,
Digital Wave Systems Lab,
Atlanta, Georgia, USA,
2007--2019,
Available at http://hallertau.cs.gsu.edu/calq_latest.
It's the same information, just in a different format.
If you need to do this in APA, MLA, or some other format, simply change it as
needed.
Citing is important for people like me! It's the academic equivalent of
a "like" button on social media. The more citations, the bigger the impact,
and the more we are encouraged to continue to do it.
For other projects, change the title, year, version and URL as appropriate.
