TL;DR
A PDF titled "LaTeX Coffee Stains (2021)" is available at a CTAN URL, but the source excerpt says the full article text is not available. No substantive content from the document can be confirmed from the provided source.
What happened
A document titled "LaTeX Coffee Stains (2021) [pdf]" was identified at a CTAN-hosted URL. The short excerpt available with the listing contains the word "Comments" and an explicit note that the full article text is not available, leaving the substantive contents of the PDF inaccessible from the provided source. The file path in the URL places it under CTAN's graphics/pgf/contrib/coffeestains directory, which confirms the file's hosting location but does not provide the document body or detail what topics or examples it covers. Because the underlying PDF content could not be retrieved from the provided excerpt, any claims about the document's scope, purpose, examples, or associated code would be speculative. Where the source does not supply facts, those points are labeled "not confirmed in the source."
Why it matters
- Availability of primary documentation affects researchers and users who rely on CTAN-hosted resources for reproducing typesetting or graphics workflows.
- When a listed PDF lacks accessible content, users cannot verify examples, usage notes, or implementation details that might accompany a LaTeX contribution.
- The CTAN location indicates the item is archived alongside other TeX/LaTeX materials, but the actual contents are not confirmed in the source.
- Incomplete listings on archive sites can slow adoption or correct use of community-contributed tools and examples; specifics about this document are not confirmed in the source.
