When scanning your old photos and scrapbooks, there are plenty of services that can do them for you. However, there is a risk when using these services and shipping your items to them. Ideally, you would want to take your items to a local photo company that will do it in-house and not ship it anywhere.
However, you can very easily do it yourself now and days with a scanner/printer you can purchase for fairly cheap. You can also use your smartphone and tablet to digitize your photos and scrapbooks very easily now and days too. You can then take your digitized photos and add captions or metadata to them through applications such as MAGIX Photo Manager Deluxe or Photo Mechanic.
