I went to a website on google called Society of Professional Journalists and it had the SPJ's code of Ethics in complete tet to read and then it also gave you resources. For example an ethics hotline. They also provided a "reading room" where you can check out relevant artices.
There were tons and tons of websites and articles on ethics. The text is very straight forward, making it a very important topic that all journalist should know and have read about.
I read a little bit about the Poyntor Inst. as well. i hadn't heard of it nor did i know what it offered until i did this exercise.
