Is there a formal description for the bibtex format one can use for writing tests, evaluating libraries, writing libraries etc? For these the description needs to be very clear and definitive, what characters are allowed etc. So far, I have not found an official, formal description of the bibtex format.
I assume this is the official website:
In a comment, I got the tip to search on https://texdoc.org/index.html
Searching for "bibtex format" has no results.
Examples:
- In bibtex files (.bib), what are allowed characters in the citation key? See also Bibtex's formal format for citation key field
- Is the citation key optional or must it exist?
I have seen entries like this, supposedly created by Citavi:
