For example, we are in the process of converting TIFFs of scanned documents (that are no longer available as word processing files, some dating back to 1891) to PDFs so that the public may download a single PDF rather than view a page at a time using a server-based TIFF viewer.
Wonderful...
What I have been doing is to clean up the scanned pages (deskew, remove artifacts, etc) and PDF the first page. I then drag the remaining TIFFs into the PDF. At times, this PDF can be up to 250Mb. I then "refry" the PDF and it will come down to a more reasonable 60Mb (still large but often these documents are 300 - 400 pages in length).
Take a look at the new PDF Optimizer in Acrobat 6 Professional or PDFCompressor from CVision as both use a modern technology called JBIG2 that will get your files EVEN SMALLER for black & white/monochrome scans...
Also, Acrobat 6's PDF Optimizer has an even cooler technology called "Adaptive Compression" that does wonders on color scans.
Furthermore, sometimes the pages are off-center, ie too far to the left or the right. What we have futher adopted to our practice is to crop the TIFF to just the text area which of course is smaller than 8.5x11, sometimes, with bound books, the text area is about 5x8.
You might want to look at the tools from Image Solutions, which offer many scanned PDF improvement features...
