Analytical Archaeometry describes this interesting and challenging field of research - on the border between natural sciences (chemistry, spectroscopy, biology, geology) and humanities (archaeology, (art-)history, conservation sciences). It fills the gap between these two areas whilst focussing on the analytical aspects of this research field. The first part of the book studies the main analytical techniques used in this research field. The second part expands from the different types of materials usually encountered, and the final part is organised around a series of typical research questions. The book is not only focussed on archaeological materials, but is also accessible to a broader lay audience. Overall the book is clearly structured and gives insight into different approaches to the study of analytical providing extensive discussion on a wide range of techniques, materials, questions and applications. Due to the advances in analytical instrumentation and applications in this field, it is important to have all this information merged together. Academics as well as professionals in archaeology, art history, museum labs and conservation science will find this an invaluable reference source ensuring the reader is provided with the latest progress in this research field.

Saint-Malo 1944: Marie-Laure, ein junges, blindes Mädchen, ist mit ihrem Vater, der am "Muséum National d'Histoire Naturelle" arbeitet, aus dem besetzten Paris zu ihrem kauzigen Onkel in die Stadt am Meer geflohen. Einst hatte er ihr ein Modell der Pariser Nachbarschaft gebastelt, damit sie sich besser zurechtfinden kann. Nun ist in einem Modell Saint-Malos, der vielleicht kostbarste Schatz aus dem Museum versteckt, den auch die Nazis jagen. Werner Hausner, ein schmächtiger Waisenjunge aus dem Ruhrgebiet, wird wegen seiner technischen Begabung gefördert, auf eine Napola geschickt und dann in eine Wehrmachtseinheit gesteckt, die mit Peilgeräten Feindsender aufspürt, über die sich der Widerstand organisiert. Während Marie-Laures Vater von den Deutschen verschleppt und verhört wird, dringt Werners Einheit nach Saint-Malo vor, auf der Suche nach dem Sender, über den Etienne, Marie-Laures Onkel, die Résistance mit Daten versorgt & Kunstvoll und spannend, mit einer wunderschönen Sprache und einem detaillierten Wissen um die Kriegsereignisse, den Einsatz des Radios, Widerstandscodes, Jules Verne und vieles andere erzählt Anthony Doerr mit einer Reihe unvergesslicher Figuren eine Geschichte aus dem zweiten Weltkrieg, und vor allem die Geschichte von Marie-Laure und Werner, zwei Jugendlichen, deren Lebenswege sich für einen folgenreichen Augenblick kreuzen.
