Hi Ihor.

Then, is it not possible to customize the entry generated with org-bibtex-create?

> #+begin_src emacs-lisp
> (defun my-org-bibtex-headline-format (entry)
>    "Custom function to generate the headline text for org-bibtex-write."
>    (let* ((title (cdr (assoc :title entry)))
>           (author (cdr (assoc :author entry))))
>      (concat "Mi encabezado personalizado: " title " - " author)))

> (setq org-bibtex-headline-format #'my-org-bibtex-headline-format)
> #+end_src

This is correct, but this customization only works in
`org-bibtex-write', which works together with `org-bibtex-read-buffer' /
`org-bibtex-read-file'.

`org-bibtex-create' hard-codes heading to be the same with BiBTeX :title
field.

Yes, org-bibtex is not very polished.
