Since this is not my area of expertise, I searched Google under the key words "'plate boundaries'" to get these possible sources:

http://scign.jpl.nasa.gov/learn/plate4.htm
http://pubs.usgs.gov/gip/dynamic/Vigil.html
http://en.wikipedia.org/wiki/Plate_tectonics
http://www.classzone.com/books/earth_science/terc/content/visualizations/es0804/es0804page01.cfm?chapter_no=visualization
http://www.cotf.edu/ete/modules/msese/earthsysflr/plates1.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps a little more. Thanks for asking.
