About two years ago a good friend of mine died. He was once a history professor at the University of New Mexico, and because his family knew he and I used to ramble on about history, they gave me his heavily annotated copy of The Columbia History of the World [x].
After two years of gathering dust on my shelf I decided to pick it up and leaf through it. From what I read, skimming excerpts at random, I found the style enjoyable--and his annotations entertaining and intimate in that used-book sort of way.
Now I'm no historian, just a fan of history, but regardless the book is over 30 years old and I was wondering how wary I should be going into it.
You should not be wary of any general history survey book like this, just because it is thirty years old. However, if there is an area that really piques your interest, you should try and find a more recent history book, that focuses on that area.
