Two questions
editI noticed you added a lot of new material in the reward system article using a college-level textbook (An Introduction to Brain and Behavior by Kolb & Whishaw). I have two quick questions for you in relation to those edits:
- Can you tell me what the 10 or 13 digit ISBN for the textbook that you're using is? I only need one of those numbers to correctly format the references that you added; these numbers are usually located on one of the first few pages of a textbook and are typically listed as "ISBN-10" or "ISBN-13".
- Are you editing Wikipedia as part of a class assignment for academic credit?
Thanks for your contributions.

It looks like the material may have been copied from drugabuse.gov/publications/drugs-brains-behavior-science-addiction/drugs-brain, a public domain web page of the US Government. You are welcome to import appropriate public domain content to articles, but in order to meet the Wikipedia guideline on plagiarism, such content must be fully attributed. This requires not only acknowledging the source, but acknowledging that the source is copied. There are several methods to do this described at Wikipedia:Plagiarism#Public-domain sources, including the usage of an attribution template. Please make sure that any public domain content you have already imported is fully attributed. — Diannaa 🍁 (talk) 12:39, 13 March 2017 (UTC)
