Hi. Where I can find this book?
I am surprised to find this as an ebook on Amazon: https://www.amazon.com/Inorganic-Chemistry-Approach-William-Porterfield-...
It was certainly not available in quantities that you could assign to a class about 10 years ago when I read and loved this text. I found the explanations to be particularly clear and it was the text I used to relearn a lot of Inorganic Chemistry to be able to teach it.
