You may want to look at the new "tagged Adobe PDF" and the tools for
making PDF more "accessible."
Tagged Adobe PDF
Adobe Acrobat 5.0 software introduces tagged Adobe PDF, an enhancement to
the PDF specification that allows PDF files to contain logical document
structure. Logical structure refers to the organization of a document,
such as the title page, chapters, sections, and subsections. Tagged Adobe
PDF documents can be reflowed to fit small-screen devices and offer better
support for repurposing content. They also are more accessible to the
There is a free plug-in for Acrobat (full application, not the Reader) to
"Make Accessible" which apparently creates "tags" and makes sure the text
is in reading order. A plug-in for Word will let you use Word styles to
create "tags" and bookmarks.
I suggest that you "may" want to look at it in the hope that you will tell
those of us interested in the preservation challenge what you find. I
found this stuff about 10 days ago when trying to construct a usable (and
accessible) PDF from a structured Word document and hypothesized that
features that enhance accessibility would enhance preservability too.
