If you've pre-registered for an appointment, all you need to do is head straight to the scanning station with a sign announcing "Pre-registration" at your appointment time, give the volunteer your name, and you're good to go!
If you're a drop-in appointment, you'll find a sign-in area at the entrance to the digitization area. When you sign in, you'll get a number, and you'll be called to the next available digitization station (of four we'll have open to drop-in appointments) as soon as your number is up. Feel free to wander around the Museum and listen in on the presentations as you wait, but please don't leave the Museum building, as we'll have to move on to the next number if we can't find you when it's your turn.
Once it's your turn for scanning, the digitization volunteer will ask if you'd like to digitize your materials yourself--in which case they'll walk you through the process, step-by-step--or if you'd just like to observe, which is fine, too. If any of the materials you've brought in are oversized, you'll stop by the overhead photography station, too, so that we can take a high-resolution image of the item.
