The year refers to the camp that happened in January of that year.
If you have photos of the camp that you think we don't have, please either give a CD or flash drive with the photos on to Aidan Horn, or upload them to a cloud storage and share them with annualhermanuscamp[at]gmail.com . We store our photos in Google Drive and manage them with Google Photos, so that cloud is preferred (this can be done with Backup and Sync). We do not have photos from the 2016 and 2017 camps.
The years 2000–2006 have not yet been scanned from the Doomsday Book III, but if you have digital photos from those years, they are also welcome.
