I would like to have part of an article have
text/analysis while being
able to see the PDF original source of the information side by side.
Couldn't you provide a link to the PDF so that the user can open it and
put it side by side if they choose? Personally I'd find it very
annoying to have a different document open in the middle of a web page
(this is the main reason why I don't use any PDF plugins in my browser,
I much prefer files like this opening in a separate program.)
Cheers,
Adam.
