Barack Obama wasn't the only beneficiary of the calamitous Bush years. Something of an industry punchline since its formation in 1996, MSNBC suddenly gained a comprehensible voice during the era, while pinning its hopes upon the inspiring senator from Illinois. Obama's victory spelled success for the network, which saw a sizable ratings increase and began positioning itself as a viable alternative to the right-wing propaganda of Fox News. However, a close inspection of the station's programming and an analysis of their celebrity hosts generate troubling questions about the state of the American media. MSNBC has shilled for Obama's wars, defended the administration's illegal spying programs and failed to hold our broken political system accountable. Medium Blue serves as a primer to help navigate the ultimate futility of our distinguished liberal media.

Gemstones is the first attempt in English to bring together the geological, mineralogical and gemmological developments that have taken place during the last thirty years. Though there have been many gemstone books published in that time, most have been concerned, understandably and rightly, with the science of gem testing and have covered that area very well. Details of the geological occurrence of many of the classic gemstones, and of nearly all those which have only recently been discovered, have been less adequately dealt with. Coverage has been restricted to a number of papers in a wide variety of geological and mineralogical journals. Gemstones hopes to get the balance right. In the preparation of the book all the journals and monographs in the field have been consulted so that the book should stand for some years as the authority to which gemmologists and others turn in the first instance. Ease of reference and depth of coverage make Gemstones both a reference book and a bench book.
