Looking at the document, my case looks more interesting.

As I noted, the two sets of appendices are mostly completely different. 
There are 9 appendices that look like they are from the primary document 
and 5 that look like they are from inserted pages. Both sets start 
numbering from "A". There is one title shared between the two sets.

But the really interesting thing is that the copyright date on the 
"primary" document is AFTER the date in the footers of the "inserted" pages.

FYI - the document is Computervision CADDStation System Software 

So, any recommendations on what I should do?

Also, any recommendations on a software tool to slice and dice PDFs that 
is inexpensive?
