The Stacks project

How to cite tag 0213

Go back to the tag page.

You can use one of the following citations in your LaTeX code.

• \cite[\href{https://stacks.math.columbia.edu/tag/0213}{Tag 0213}]{stacks-project}
• \cite[\href{https://stacks.math.columbia.edu/tag/0213}{Lemma 0213}]{stacks-project}
• \href{https://stacks.math.columbia.edu/tag/0213}{Tag 0213}
• \href{https://stacks.math.columbia.edu/tag/0213}{Lemma 0213}

You can use the following in your BibTeX file.

@misc{stacks-project,
  author       = {The {Stacks project authors}},
  title        = {The Stacks project},
  howpublished = {\url{https://stacks.math.columbia.edu}},
  year         = {2025},
}

You can also consider using the @online type in BibLaTeX, changing the the howpublished to url. Another neat trick in BibLaTeX is the shorthand field, which you could set to SP or Stacks.
