How to use polite pool in content_negotiation?

[Xunius]

Hi,

I'm currently developing a reference manager tool and I'm learning how to use Crossref. For now I only need to use the content_negotiation() function to get an bibtex entry from DOI. I saw the "The Polite Pool" section in the doc of Crossref, but no relevant info in content_negotiation(). How should I ensure polite pool practices using content_negotiation()?

Thanks

thanks for the issue @Xunius

"Polite pool" only exists for the Crossref API at https://github.com/CrossRef/rest-api-doc - which is what most of the methods in the habanero.Crossref module work with. For content negotation, requests of all formats (except one) go to a different place, documented at https://crosscite.org/docs.html . The only format that goes to the Crossref API, and where the polite pool applies, is the citeproc-json format.

side note that we actually send the mailto header with the user email with all content negotation requests, but it should only have an effect when format = "citeproc-json"
