::As for the vol./edition issue. Maybe in English there is a way that "vol. 6" can be easily confused with "6th edition"; not in Portuguese. It never crossed my mind that a quote like "O Povo Brasileiro, vol. 6" could refer to the 6th edition of such book. Maybe I am stupid. But I tried page 6, the chapter that would be number 6 if they were numbered, and, when I found an online copy, the sixth webpage of the several into which it was divided. None of those revealed the content that supposedly should be there, so I read the whole book. And the content was still not there. And yes, I have asked for the page, or chapter, or paragraph, or whatever other way to locate the alledged content, in this and in other similar cases; the most polite and informative answer I got was complete silence.
