Re: CrossRef utils in TL'26 are broken

Hi Paulo Ney

As Karl said, maybe we should move this discussion elsewhere.  In
the case some people here use crossrefware,

PNdS> bidzbladd fails more drastically:


1.  bibmradd works for me.  Could you please run it in debug mode (as
bibmradd -d) and catch the output?  Please put it as a comment in the
github issue Karl opened.

2.  bibdoiadd seems to fail for books, but work for inproceedings and
articles.  I need to investigate why.

3.  bibzblmath is a sad story.  Zbmath seems to add a check whether
the query is generated by a robot, and the script fails.  I blame the
AI trainers that scrap internet without ethical (or any) constraints.
My own sites are constantly hit by these robots. Well, these are the
times we live in...
