Too verbose and no excitement in the writing. . As a Vietnam Veteran who was there in 1963 the flavor of the writing was drab and did not convey what was really going on from the perspective of the ordinary GI. Yes, there were some historical facts and biographical  info that was interesting but something was missing. I read about 25 pages  and gave up

Stay Clear of Lonely Planet . A hopeless mess of headlines and confusing comments, very little structure.  No rankings of what you should see and do, no pictures, no useful restaurant and hotel recommendations.  Endless yatter about nothing makes this a boring read with almost no real content.  Absolutely worthless on our Japan trip to Tokyo and Kyoto.  This is not the first time we have been disappointed by Lonely Planet. They cater to backpackers only, usually looking for the cheapest accomodation and meals, and with no value added for the traveller who is short on time but still wants to make the most out of his/her time.  We ended up buying the Eyewitness Guoide which is fast and easy to use.

don't know what I'd do without it! . I'm a science copyeditor, and I truly don't know how I'd manage without this book. If it has to do with chemistry, it's here (thank heaven!). And there's a wealth of clear information about how to format math, a wonderful list of unit abbreviations, and even a fair amount about physics- and biology-related terminology. It has the most lucid and concise explanations I've seen about when to apply italics or roman. And it's reasonably priced. Of course, if you specifically need to follow ACS style, this book is de rigeur, but even if you don't, you'll find it invaluable for science copyediting
