Help wanted: Digital citizenship resources?

I recently got this message from an international school:

I've organized [our] Tech Leadership Team to discuss and develop a Digital Citizenship program for our school. There are 27 members of the TLT and they will be exploring 6 elements, identifying issues associated with the element, brainstorming examples of appropriate and inappropriate use, developing guidelines for use (e.g., guidelines for e-mail, cyberbullying, social networks, piracy, health), and identifying how the concept and guidelines should be shared with the community.

1. Digital Communication
2. Digital Etiquette
3. Digital Law
4. Digital Rights & Responsibilities
5. Digital Health and Wellness
6. Digital Security

I'm looking for a good book for them to read -- any recommendations?

What resources have you found valuable regarding digital citizenship? Here’s my contribution…
