Is there today an easy way to achieve the following with biblatex and biber discussed here?

Unfortunately the code does not work for me as pdflatex produces an error after successfully doing a pdflatex+biber+pdflatex run of the code stated (without showing the footnotes) telling

! Undefined control sequence.
<argument> \cbx@sortlist  

It would be so helpful to have a command like \sfcite showing a sorted list of cites occuring on one page in the footnote area of that page and a complete reference list at the end of the document...

Sorting has changed a lot since that answer was written. Change the definition of \cbx@sortlist@init to

  \global\letcs{\cbx@sortlist}{blx@dlist@entry@\the\c@refsection @\blx@refcontext@context}}

This will work for both Biber and the deprecated BibTeX backend.

The original answer in Repeat the same reference in footnote on different pages has again been updated to reflect the changes, it now works with biblatex 3.11/Biber 2.11.

  • It might be wise to edit the previous answer, since it is a popular one. Mar 27, 2017 at 16:01
  • @PaulStanley I'm not very keen on editing other peoples' answers (especially those where I can't claim to have fully understood everything that is going on), but you might have a point there.

  • Generally I agree but if the code is actually broken as this is, and you (among I'd guess a tiny number of people) know how to fix it as you do, and the question obviously gets quite a lot of visitors, I think I'd make an exception! Mar 27, 2017 at 16:46
  • Unfortunately the code above once again throws the error '! Undefined control sequence. <argument> \cbx@sortlist' as I wanted to reuse the code again. Did again the soring change over the last year? Is there even a built-in solution to biblatex now I am not aware of? Thanks for your help!

  • @fermikante Yup, the macro names have changed again. I updated this answer here and also edited the original answer. Incidentally, just the same change was also relevant in tex.stackexchange.com/q/420394/35864
