Would that neat join trick also work in https://github.com/Humans-of-Julia/Bibliography.jl/blob/b23a0265a5e6ea4a5bad4e656d5699a458cc2fdd/src/staticweb.jl#L66-L133 ?

I noticed in your example that it might be useful.

Edit:
And

Bibliography.jl/src/staticweb.jl

Lines 142 to 154 in b23a026

	"""
	xlink(entry)
	Format the download link of an `Entry` for web export.
	"""
	function xlink(entry)
	if entry.access.doi != ""
	return "https://doi.org/" * entry.access.doi
	elseif entry.access.url != ""
	return entry.access.url
	end
	return ""
	end

could also return the arXiv link.

The arXiv link can be removed from the issue. There is no arXiv field in the BibTex spec and it is recommended to use archivePrefix and eprint field to cite that correctly. So the current workaround to get a url via DocumenterCitations.jl should be to add the arXiv link to the BibTex url field.

For the empty fields with commas my only solution would be to throw a lot of addstr != "" ? ", " : "" onto it.
I think there might be a more elegant way but join might not work here.

Nevertheless this might be fixed or vanish after you add the custom cite/bibliography formats you mentioned somewhere else.
