Frequently Asked Question List for TeX
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 that 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:
plainpages=falseMake page anchors using the formatted form of the page number. With this option,
hyperrefwrites different anchors for pages “ii” and “2”. (This is the default value for the option, which is a good thing…) If the option is set
hyperrefwrites page anchors as the arabic form of the page number, rather than the formatted form that gets printed; this is not usually appropriate.
pdfpagelabelsSet PDF page labels; i.e., write the value of
\thepageto the PDF file so that Acrobat Reader can display the page number as (say) “ii (4 of 40)” rather than simply “4 of 40”.
The two should be used whenever page numbering is not just “1…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.
