This is the best concise compendium of original Buddhist teachings available in (smooth) English, in my opinion. The selection is excellent and covers the full range of Buddhist traditions. The titles are generally thematic, leaving the designation of the actual sutra to a small note at the end of each selection. It is the perfect and most natural choice for those who are looking for a small bedside edition of concise Buddhist teachings rather than a complete translation of the entire Majjhima Nikaya, or some such (for that check out Wisdom Book's excellent Middle Length Discourses of the Buddha, for example). In short, I can't recommend this book highly enough!
