You can also consider buying a scanner if you are going to do a lot of scanning, but they are pricey themselves, running often about $1000. You may also need a large format printer. We had both at the museum where I used to work as we needed that ability both for exhibit production and for scanning the contents of the archives.

However, if you have the time and the inclination, you can scan each page four times and then “stitch” the parts of each page together to get the original layout in digital form. You can also do what I do at home – I scan the individual photos and then create a digital scrapbook through resizing, cropping, and cut-and-paste. I use a cheapo $99 Epson scanner to do that as we don’t print out the resulting album but put it on CD for anyone who needs it.
