Sadly, Spry, old boy, your scanning has let you down. Looking at your Tee-Emms, it looks like Command Graphics or Repro-Graphics have scanned each page as a picture - hence they are ~9 mega bytes for a small 15-odd page document! If they had used OCR (optical character recognition) and scanned the pictures as JPGs then the files would be less than 2 mega bytes.
I suggest that you get them to scan the Air Clues and Tee-Emms to a more manageable size.
