Hyperref and repeated page numbers
The book 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 if
hyperref has been misconfigured, the existence of pages have
the same page number can cause problems. Fortunately, the
configuration options to make hyperref “do the right
thing” are (by default) set up to avoid problems.
The two options in question are:
The two should be used whenever page numbering is not just
- Make page anchors using the
formatted form of the page number. With this option,
hyperref writes different anchors for pages ‘ii’ and ‘2’.
(This is the default value for the option, which is a
If the option is set ‘
true’ hyperref writes page
anchors as the arabic form of the page number, rather than the

..n’; they may be used independently, but
usually are not.
The recipe isn’t perfect: it relies on
thepage 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 “duplicate destinations”
will happen in this case, regardless of the options.
