We purchased the 1999 edition directly from Moon (it was so new Amazon had not received it yet) hot off the press ! We also purchased several other competitors guidebooks to take with us. The Costa Rica Handbook came back from the trip very worn! Of all the books, this one has the most travel information, the best maps, most useful suggestions and funny traveler's stories that were relevant to our trip. We tried using and referring to the other books many times while in Costa Rica, but we found ourselves reaching for the Costa Rica Handbook by Moon time and time again! If you can only afford to buy one book with information on travel to this country buy this one! One shortcoming you should conisder before buying this book - it contains little about wildlife...you will need to purchase another book that contains pictures and identification information about animals, plants, insects, birds, etc. of this country if your primary purpose for going is to sight animals and birds native to Costa Rica ! Another note: If you are planning on driving outside of tourist areas you might want to learn a little Spanish...we speak intermediate Spanish and while I was in the country, I couldn't help thinking that someone who had no knowledge of the Spanish language would find traveling by car and stopping outside of tourist areas (lodges, restaurants and gas stations) a bit confusing (they speak almost no english outside of tourist areas)...Know your road signs in Spanish! it helps a lot - buy a beginner's guide to Latin American Spanish with a tape so you can hear pronounciation.
