How to cite

Cite the version you used. Version links never change, so a reader can always see the exact numbers you relied on.

Links

URL	Points to
`/c/<id>/v/<version>`	One version. Never changes. Cite this.
`/c/<id>`	The latest version. Changes when the entry is revised.
`/api/c/<id>/<version>.json`	One version as JSON.

Every entry page has its own citation and BibTeX under Cite this, with a copy button. The examples below use Rooftop unit, gas heat / DX cooling.
