The first time I typeset this I get ?? for the \ref. The second time, it is blank. I am using TeXShop. I set out to make an example that uses biblatex to get a list of references for each chapter and another list at the end of the book. It makes the reference lists OK, but not the \ref marks. What is wrong?


 \chapter{First chapter}\label{ch01}
 Some text \citep{Duffie:96}.
 Refer to \ref{ch01:sec01} of chapter \ref{ch01}.

 \chapter{Second chapter}
 Some text\autocite{Eason1999}. 
 Remember section \ref{ch01:sec01} of chapter \ref{ch01} down here.

This,\autocite{hashemian} should be a side note but not this \citep{hashemian}.


Here is references.bib:

The chapter and section headings are unnumbered in the tufte-book document class. Since \ref wants to print the chapter/section number and can't find it, it complains in the log file:

Package hyperref Warning: Suppressing empty link on input line 18.

If you turn on the chapter and section numbering (by adding \setcounter{secnumdepth}{1} to the preamble of your document), it should fix the problem.

Note, however, that the headings in the tufte-book aren't designed to print the numbering nicely by default, so you may need to fiddle with the formatting a little bit.

As an alternative, you might consider using \nameref instead of \ref to print the name of the chapter/section instead of the number.

  • Thank you. That solved the problem. I am using \setcounter. – Sam Cox Feb 19 '16 at 15:47

    +1 for the \nameref suggestion. Just what I needed to know. – twip Oct 3 '16 at 15:36
