Design Knowledge - Something I have never known

Who can say design is not significant in the modern world?
Sometimes, I hear about Design and its impact on the usability and the beauty of things. However, there  is no opportunity for me to dig in deep the designers' world. Fortunately, I read an article from procul.org/blog which discusses about how should the toilet be designed. According to that, I obtained several books for training the design aspect myself (i.e autodidacticism). They are:

1. The Design of Everyday Things by Donald A. Norman for general topic
2. Don't Make Me Think by Steve Krug for web design
3. Designing the Obvious: A Common Sense Approach to Web & Mobile Application Design 

I hope that they will be covered as soon. Definitely that!
