From the comfort of your home, YOU can help create the digital transcription of the Oxyrhynchus Papyri (documents written in Greek and found in Egypt). All you have to do is check out images of the papyrus fragments and help recognize the Greek letters visible on the fragment; you don’t even have to be able to read Greek.
Check out the Ancient Lives site and get started. They have a great tutorial to help you understand how it works.
You can also check out a good description of the project from Citizen Science here.
