Theses, Books, Title pages ⇒ Hyperref not going to the right place.

[CMP]

I am managing Bibliography via "natbib" package but eventually when I click on the cited reference in the main document then it does not direct to the proper number in the Bibliography section. But it just go back to the front page.

Here is my MWE:

Code: Select all

\documentclass[12pt,openany,letterpaper]{book}
\usepackage[T1]{fontenc}
\usepackage[round,sort,comma]{natbib}
\newcounter{bibcount}
\usepackage{hyperref,url}
\usepackage{color}
\usepackage[english]{babel}
\usepackage[autostyle, english = american]{csquotes}

\newcommand{\red}{\color[rgb]{1,0,0}}
\hypersetup{,colorlinks=true,allcolors=red}

\setlength\bibindent{10cm}
\makeatletter
\patchcmd{\@lbibitem}%
{\item[}%
{\item[\hfill\stepcounter{bibcount}{[\thebibcount]}}%
{}%
{}
\patchcmd{\@lbibitem}%
{\hfil \NAT@anchor {#2}{\NAT@num }]}%
{]}
{}
{}
\setlength{\bibhang}{2.00\parindent}
\renewcommand\NAT@bibsetup[1]{%
	\setlength{\leftmargin}{\bibhang}%
	\setlength{\itemindent}{-\parindent}%
	\setlength{\itemsep}{\bibsep}%
	\setlength{\parsep}{\z@}}
\makeatother

For example, when we click on "Ash (2000)" [img]

Ash.png (6.68 KiB) Viewed 10626 times

[/img]on page 3 it should go to #3 in the Bibliography section but instead the document pop up to the first page.

I am wondering what is going wrong here and how to fix it.

Thank you!

What happened is, that you're patch removed \NAT@anchor, which not only prints the your-year label but also adds the hyper anchor. That they are missing is reported in the log-file:

pdfTeX warning (dest): name{cite.MR1034353} has been referenced but does not exist, replaced by a fixed one

pdfTeX warning (dest): name{cite.MR1810041} has been referenced but does not exist, replaced by a fixed one

pdfTeX warning (dest): name{cite.ds14} has been referenced but does not exist, replaced by a fixed one

pdfTeX warning (dest): name{cite.n97} has been referenced but does not exist, replaced by a fixed one

After re-adding at least the hyper anchor generation from NAT@anchor, the links are correct:

BTW: IMHO such mixture of author-year style in the text and numeric style in the bibliography does not make much sense. Because, if the numbers in the bibliography are not referenced, they are superfluously. And searching for the correct entry in the bibliography is hard, because the distance between name and year is not only wide but also differs from entry to entry. So if you are not forced to use such a mixture, I would recommend to use either a author-year style of a numeric one but not such a mixture.

BTW: Usage of biblatex + biber would not only allow to use UTF-8 also for the bib-file but mostly provide much more features and configurability without bst-hacking. Because of this, in our days, it is often recommended to use biblatex and biber instead of natbib and BibTeX.

Thank you very much, Ijon Tichy!

It really solved my problem.

I do not use author-year citation in the document and numbers at the end in my research.
But usually for class room materials, I use it just for simplicity to talk about
the materials in some references by referring to the number.

I greatly appreciate for all the additional comments you made there including hacking issue.

One more request, could you please recommend me an excellent reference book(s)
which could be very helpful to keep in our shelve and make it handy whenever we
need?

Thanks aagain!
