Not much time these days to thank you for your help, specially Ihor, András, Eric.

After thinking about it, I think I will maintain 2 files by now: 1.bib and 1.org. with my highlights and other notes.

Best regards :-)

 The processor relies on the external Citeproc Emacs library, which must be available prior to loading this library.

Should we add something to this? If yes, what is missing in your opinion?

I saw this comment, but I was not sure which library it referred to.
First, I looked in built-in Emacs libearies. No luck. Then, I tried
search ELPA, but still no luck. Same for NonGNU ELPA. Then I tried web
search and saw github/citeproc-el. It confused me, because it is not
exactly "Citeproc Emacs library", but rather "A CSL 1.01 Citation
Processor for Emacs.". I had to look at source file names to verify.

A link to the library source code would be helpful.

Also,

;; Bibliography is defined with the "bibliography" keyword.  It supports files
;; with ".bib", ".bibtex", and ".json" extensions.  References are exported using
;; the "print_bibliography" keyword.

If there is support of ".org", it could be mentioned (with caveats, I guess).

Best,
Ihor
