Bibupdate – Automatically update the entries in a BibTeX file

This is a command line tool for updating the entries in a BibTeX file using the free tools provided by the American Mathematical Society: mrlookup, MathSciNet and MRef. By default bibupdate uses mrlookup to update article, book, inproceedings and incollection entries when they do not have an mrnumber field. Entries are not updated if they already have an mrnumber field, even an empty one, unless --all or --check is used. With the -X option, bibupdate looks for each paper in the arXiv and adds eprint and archiveprefix fields for all the papers that it finds.

By default, bibupdate writes the updated entries to a new file, with the filename given by adding an updated_ prefix. To update the bib file in place, use the --overwrite option. This should be used with care because you can potentially lose data.

The tool requires Python 3.9 or later.
