I will probably buy it in the next year (sadly, it is not available in the library of my town). I would like to know if Durant's book is still trustable and actual/current according to modern patterns of historiography.
Keep in mind i will spend around 250 dollars, because i live in Brazil.
/u/bodark43 and /u/keloyd offer some commentary on Durant's work here. You might also find the "general history" section of the subreddit booklist helpful.
It is hard to call the Durants' series up-to-date. They are well-written and engaging, though, and some are still worth reading. If English is your second language, they might be easier than something more academic. The ones on ancient history are hopelessly obsolete, and the Age of Faith and The Renaissance are pretty Eurocentric. The last two , on revolution and Napoleon, don't do much on the economics of the times and I think now most people would call that a big problem.
Volume 6, on the Reformation, to volume 9, on the Enlightenment, would still be worth the $4-$5 price per paperback volume that they go for over on AbeBooks. I would certainly hope that shipping those four books to Brazil would not cost you hundreds of dollars!
