Dont you have the decency to recognize a mistake Mathsci If you look on Amazon you will see that the author of the book you recommend Frederic P Miller specializes in compilations of Wikipedia articles and labels his books High quality content by Wikipedia articles Im afraid this goes to show the doublestandards of your attitude about sourcing pompously asking of others the sourcing quality of a doctoral thesis but when it fits your own convenience putting forward the first source that props up on Internet even if just a republisher of Wikipedia articles A word of apology would be OK though as well as a more tolerant attitude towards my own contributions nobodys perfect and I do appreciate your work otherwise Best regards
