<h3><i>Hyperref</i> and repeated page numbers</h3>
<p>The <i>book</i> class (and its friends and relations) automatically
changes the display of page numbers in the frontmatter of the document
to lower-case roman. This is fine for human readers, but it confuses
<i>hyperref</i> since there are pages which seem (to
<i>hyperref</i>) to have the same page number. Fortunately, there are
configuration options to make <i>hyperref</i> "do the right
thing".
<p>The two options in question are:
<dl>
<dt><code>plainpages=false</code><dd> Make page anchors using the
formatted form of the page number. With this option,
<i>hyperref</i> writes different anchors for pages 'ii' and '2'.
(If the option is set '<code>true</code>' - the default -
<i>hyperref</i> writes page anchors as the arabic form of the
absolute page number, rather than the formatted form.)
<dt><code>pdfpagelabels</code><dd> Set PDF page labels; i.e.,
write the value of <code>\</code><code>thepage</code> to the PDF file so that
<i>Acrobat Reader</i> can display the page number as (say) 'ii (4
of 40)' rather than simply '4 of 40'.
</dl>
The two should be used whenever page numbering is not just
'1<code>..</code>n'; they may be used independently, but usually are not.
<p>The recipe isn't perfect: it relies on <code>\</code><code>thepage</code> being different
for every page in the document. A common problem arises when there is
an unnumbered title page, after which page numbers are reset: the
PDFTeX warning of "<a href="FAQ-hyperdupdest.html">duplicate destinations</a>"
will happen in this case, regardless of the options.
