Hello All,

I have a question about maps -- which I dearly love, and which I think are underutilized for educational purposes, perhaps due to licensing issues.  Forgive me if this issue has been hashed previously.

I have a friend (a lawyer turned fitness/rhythm instructor -- 
www.totalrhythm.com) who is producing a DVD.  He wants to include a map or maps, perhaps on which he would add some markings.  I did follow Mia's advice and read through the 

http://wiki.creativecommons.org/DiscussionDraftNonCommercial_Guidelines

My take is that even a map has an NC restriction, his use would not be a "primary draw". and should be OK.  I'm wondering:


1. If this specific issue has been discussed;
2. The thoughts of people on this list about the subject of maps generally;
3. Suggestions on searching for CC licensed material.  
I tried 

http://search.creativecommons.org/#  and checked the boxes, but the results did not seem to be restricted to CC licensed stuff.
http://wiki.creativecommons.org/Content_Curators does not have much on maps, but the Wikipedia entry actually lists quite a few:

I have been using the Perry-Castañeda Library Map Collection. for years and love it, and it looks like he'll be in the clear with that one.

Thanks.
