To replace a favoured book that had pages missing, very useful medical book, good for looking up symptoms that you suffer. Physicians in specialized fields provide up to date information on symptoms and diseases of all kinds The book came in very good condition and was very pleased with the literature within the book and I will receive great value for money on this subject Thank you. I really like this book It arrived quickly and in good shape, I am very please with my purchase It s not easy finding such great information it s a great addition to my library I might buy again for gifts. Bought for a friend good, informative book that might just help you find out what is going on and is much cheaper than an office visit unless you have an HMO.
