Travel book reviews are necessary, because there's probably a new travel book published every five minutes. And we can't read them all, so someone has to do it - and tell us about the best.
How to choose? I check out the best travel guidebook reviews. Each series has a different stlyle, ad different voice. They also cover different destinations - some specialize in Latin America, others a Africa-centric; some focus on cities and regions, others have broad guides that cover entire continents.
