This thread has been stretched out over 4 years and I don't want to rehash it all again and especially if you take my words out of context. But with that said, I do wish MS would add a feature that would allow us to easily combine Publisher files. Copy and
pasting a few pages is one thing, but 82 pages from 12 different Publisher files will indeed take some time and is no easy project.
My only suggestion to you is to open the clipboard. (Pub 2010 > Home tab and click the down arrow by Clipboard. Pub 2007 it is under Edit.) You can copy up to 24 objects, or in your case, 24 pages and then paste from that clipboard. This will help insure
you are pasting the correct page and make the whole process a bit more efficient.
By the way, if there are a lot of images in those 12 files I would suggest that you plan on compressing them somewhere in the workflow. An 82 page Publisher file with large uncompressed pictures might become difficult to manage if the file size is too large.
