I am wondering why bibtex-string-files is not documented inside the
docstring of bibtex-expand-strings. Same for bibtex-expand-strings not
being documented in bibtex-parse-entry.

As for using bibtex-string-files in my specific scenario, I cannot make
it work as well.

I tried the following simple test:

M-: (let ((bibtex-string-files `(,(buffer-file-name))) (bibtex-expand-strings 
t)) (bibtex-parse-entry))

The journal field is still not handled: ("journal" . "jgr")

Also, note that bibtex-string-files cannot help with situations when the
BibTeX buffer does not have an associated file.

Best,
Ihor
