Crossrefware Bundle version 2021-10-02 Scripts useful for working with Crossref, MathSciNet and Zentralblatt MATH. bibdoiadd.pl - add DOI numbers to papers in a given bib file bibzbladd.pl - add Zbl numbers to papers in a given bib file bibmradd.pl - add MR numbers to papers in a given bib file bbl2bib.pl - convert `thebibliography' environment to a bib file biburl2doi.pl - convert urls pointing to doi.org to dois ltx2crossrefxml.pl - create XML files for submission to crossref.org Bug reports, source code: https://github.com/borisveytsman/crossrefware Releases: https://ctan.org/pkg/crossrefware These scripts rely on the bibtexperllibs libraries (replace /crossrefware with /bibtexperllibs in the above urls). For an example of using ltx2crossrefxml and associated code, see the TUGboat processing at https://github.com/TeXUsersGroup/tugboat/tree/trunk/capsules/crossref. Installation: 1. Move *.pl files to the binaries directory in your system. 2. Use *.cfg files as configuration files samples. 3. Move *.1 to the man pages directory in your system. This work was commissioned by The Saint Louis University and Princeton University (Mathematics Department). Thank you! Changes: 2021-10-02 - changed TEXSELFAUTOPARENT to TEXMFROOT 2021-01-18 - all conversions moved from ltx2crossrefxml to LaTeX::ToUnicode. - config file can provide a hook for processing. 2018/04/15 - Fixed a bug in bibzbladd - Work around a bug in mathscinet 2017/11/26 - Switched to date-based versioning for the bundle. - bbl2bib now converts urls starting with http(s)://(dx.)doi.org to dois. This functionality is also provided by a separate script biburl2doi - bibadddoi now has the option to (not) canonize names Version 2.2: We now treat absent CA permissively. New debug options for bbl2bib Version 2.1a: Bug in bbl2bib corrected Version 2.1: New options to add empty doi and zbl when doi or zbl are not found to prevent repeated searches. Added bibmradd.pl Added bbl2bib.pl Version 2.0: Moved to BibTeX::Parser suite. Now we use new Zbmath interface. Now we use bibtexperllibs libraries Version 1.1: workaround for a bug with macrons in TeX::Encode
