I have scanned 30 pages and the document turned out to be about 60Mb. Is there a way to reduce this size? Can I do it without re-scanning all of the pages? Help appreciated.

You don't need eyes to see just the vision because there are always more ways and different answers to what we are used to...
 
What resolution setting and what colour setting did you choose when you did the scanning? These two are the main determinants of final file size. For example, if you chose to scan at 300 dpi in colour, yes, the files will be much bigger than if you had chosen 200 dpi in greyscale.

What did you scan (text only? text with graphics?) as this will determine whether you choose to scan in colour. What is the intended destination for the PDFs you have created? Are they to be displayed onscreen only? (100dpi is fine or even 72dpi), printed on a laser? (200dpi or even 150dpi are fine).

If you need to have the PDFs at a high resolution and in colour for offset printing, then you will have to accept the file sizes will be very large.
 
Yes Eggles is right. The file size is a direct ratio of dpi (resolution) and color. I noticed that a page scanned @ 300 dpi in black and white is anywhere from 18K-40K. (30K * 30 = 900K) It also depends on your scanner (the better ones have a color drop-out that can reduce the file size on the b&w files). You need to scan at 300 dpi. The reason for this dpi rating is that its acceptable in most environments (ie. Federal Goverment etc...). Scan the pages in B&W and you should have a decent file size.
If you don't care what format you use to save the file, you could try the tiff format instead of the PDF method. This may save you some space.
Hope this helps you.
