Don t 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 I m afraid this goes to show the double standards 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 re publisher of Wikipedia articles A word of apology would be OK though as well as a more tolerant attitude towards my own contributions nobody s perfect and I do appreciate your work otherwise Best regards
