I want to do something like that. I prefer option sorting=nyt in Biblatex. But with command \sfcite{} I don't have sort order like in References.

Question 1: Is there a way to sort \sfcite{} before they appear in text to made it work like my command?

I made something like that:

\DeclareBibliographyCategory{goodB}
\addtocategory{goodB}{ref2,ref1}

\edef\bibrule{\hrule} 
\defbibheading{rule}{\bibrule}

\usepackage[perpage]{manyfoot}

\DeclareNewFootnote{Z}
\renewcommand{\thefootnoteZ}{}

\newcommand{\printbibliographyfoot[1]}{%
   \let\footnoterule\relax%
   \renewcommand{\bibfont}{\normalsize\footnotesize}% 
   \footnoteZ{\vspace{-1\baselineskip}%
   \printbibliography[heading=rule,omitnumbers=true,category=#1]}}      

\newcommand{\printbibliographyFoot[1]}{%
   \renewcommand{\bibfont}{\normalsize\footnotesize}%
   \footnoteZ{\vspace{-1\baselineskip}%
   \printbibliography[heading=rule,omitnumbers=true,category=#1]}}

This command \printbibliographyFoot[CategoryName] is doing correct sorting but I need to add all references to category manually. It is good at the end of chapter or section.

In MWE you can notice the wrong order of references in footnote :

  • I would like to have in footnote an information about cited position only once when it appear in text with labelnumber from main References. But when I have more than one, it appear in footnote in citation order. Everything is ok except sorting. I can do it manually but this is not a desirable solution. Solution presented by \sfcite{} is doing everything what I want except sorting. – Przemek Nov 03 '14 at 19:04
  • In other words ... I don't want to change main sorting in References from biblatex package (sorting=nyt) and keep their labelnumber ... I just want to do extra sorting per page when I use command \sfcite{} to have [2] before [3] even if [3] appear before [2] in main text on page. – Przemek Nov 03 '14 at 19:25
  • I think a solution - if there is any - is going to be really complicated. Your citations are essentially created using a modified footnote command and they are created immediately when issuing \sfcite. Now in order to be able to sort (order) the references at the bottom, biblatex would have to cache the footnotes for one page and then reorder them according to the sorting in the references. Storing the footnotes temporarily (per-page) and reprocessing them afterwards is going to require quite a lot of code-wizardry. – moewe Nov 05 '14 at 07:21
  • You probably want something like http://tex.stackexchange.com/q/71526/35864 – moewe Mar 27 '17 at 16:03
  • Thank you for your interest in the topic. But it seems to me that this is not a duplicate topic. The main difference is that the \sfcite{} command places the items from the References in the order in which the command is used in the text for example [3],[5],[2]. In my topic, I looked for a solution for additional sorting according to the numbering as in References, eg [2], [3], [5] regardless of the order in which the '\sfcite{}' command or similar was used. Small References at the bottom of the page with the sorted order as in the main References at the end of the book. – Przemek Apr 04 '17 at 11:57
  • Mhhh, I'm not quite sure what you mean. If I use sorting=nyt with the solution I linked to, I get properly sorted footnotes. If you are still interested in this, please open a new question where you use the new code with sorting=nyt and show how it does not work for you. – moewe Apr 05 '17 at 13:47
