Hi! I’m teaching myself concept art, and thus I want to make sure I have a thorough understanding of industrial design. I was hoping people might direct me to resources. 
I don’t have anything on industrial design right now, so if, in your industry, there are a couple books known as being key books on the subject, I would love to hear about them. Any good, key websites would be great, too. Thanks for any answers I get!
Hi Arahmynta,
I am not sure if there any key books, because there are so many books and so many directions. I can give you two websites that give an overview of a couple of good books about ID:
Learning curves and design sketching are both excellent books, and probably one or the other is found in most Industrial Designer’s personal libraries. Home - Sketching technique books for designers
Sorry for the slow response! Thank you so much you two, I will look into the resources you posted.
