Recently I thought that maybe is a good time to try, read Grothendieck's "Tohoku paper" as a sort of inspiration for the future and to read some of the ideas of this great mathematician, which (among many of course) indisputably is one of the most inspired papers in contemporary algebra (and not only). However, because the subject is quite difficult even for experts I was thinking that maybe a book would be necessery for definitions, comments or even examples on some of the notions that this paper includes. Also, I found a translated from French to English version (by Michael Barr) and I think that is the only one that exists. Is this version the "official" or there are others?
Also, do you know if there is any book that might help me on that? Or any other papers towards that direction, that might be helpful as well?
