Engineering is a key part of the modern world, and many engineering students (and teachers) crave high-quality materials on engineering ethics. Fortunately for such individuals, the Online Ethics Center (OEC) is a great place to find such materials. The OEC became an activity of the National Academy of Engineering in March 2007, and since then their online offerings have grown significantly. The teaching and educational materials on the site are organized into sections that include "Safety and the Environment", "Employment and Legal Issues", "Professional Practice", and "Responsible Research". Visitors can also click on a glossary of terms, and even suggest a resource that might be helpful to other users.
