Possible solutions
Remove the DOI
Its useful to have the DOI included in all entries, but if they don't resolve that is a problem. To which end we might
consider removing invalid DOIs. We could perhaps incorporate this into #23 and add a comment to PRs when DOIs are found
to be invalid, perhaps even remove them if they aren't?
Improve doi2bib
We should improve the script so that queries that don't return valid BibTeX entries are dropped and only valid .bib
output that can be redirected to a file are included.
The DOI 10.1289/EHP1818 no longer resolves as noted in the entry in the
README.mditself.
