Drafted in plain language, the International Trade Terms (Intraterms) are a set of standard terms for the sale of goods. They are divided into five chapters dealing with contracts in general, international sale of goods, transportation of sold goods, abbreviated terms, and resolution of disputes. In

Die vorliegende Briefsammlungenthalt BriefevonundanWolfgangPauliwahrend der Zeitspanne 1919 bis 1929. Viele Autoren haben diese Zeit mit Recht als die "goldene Periode der Physik"betrachtet. Bis zu dieser Zeithatten die Physiker eine ungeheure Menge von Fakten iiber die Eigenschaften der Atome angesammelt, insbesondere in den Resultaten der Spektralanalyse. AIle diese Resultate wider- sprachen den Erwartungen der klassischen Physik. Zwar war das Bohrsche Atommodell, erganzt durch die Betrachtungen Sommerfelds, wohl im Stande, einige dieser Tatsachen zu beschreiben, solange es sich urn die einfachsten Atome handelte, in denen man bloB die Bewegung eines Elektrons in Betracht zu ziehen hatte, wie in Wasserstoffatomen oder in den Alkaliatomen. In allen Mehr- Elektronensystemen und in den Fragen der Feinstruktur der Spektrallinien versagte aber dieses Modell vollig, und selbst in den Einzel-Elektron-Problemen erschienen die Grundlagen des Modells als plausible, aber willkiirliche Annahmen. Dan-n kam die Quantenmechanik und anderte alles mit einem Schlag. Die Ratsel waren gelost, das Verhalten der Atome konnte mit eindeutigen und logischen Mitteln erklart und im Prinzip berechnet werden. Selten, vielleicht noch nie in der Geistesgeschichte, haben so wenig Leute soviel in so kurzer Zeit geleistet. Innerhalb weniger Jahre, von 1925 bis 1928, waren die Prinzipien festgelegt, auf denen die Spezifitat und die Stabilitat der Atome beruhen; es wurden die Grundlagen der chemischen Bindung aufgedeckt und ebenso die Grundlagen der Struktur der Metalle und anderer Festkorper. Alles fiigte sich zusammen in ein logisches Gebaude, das auf ganz neuartigen Ideen beruhte, die den Grundideen der klassischen Physik in revolutionarer Weise widersprachen.

The first volume of the History of CERN (published in 1987) dealt with the launching of the European Organization for Nuclear Research covering the period 1949 to 1954. Volume II continues the history through to the mid-1960's, when it was decided to equip the laboratory with a second generation of accelerators and a new Director-General was nominated. It covers the building and the running of the laboratory during these dozen years, it studies the construction and exploitation of the 600 MeV Synchro-cyclotron and the 28 GeV Proton Synchrotron, it considers the setting up of the material and organizational infrastructure which made this possible, and it covers the reigns of four Director-Generals, Felix Bloch, Cornelis Bakker, John Adams and Victor Weisskopf.
Three considerations are relevant to the treatment of the material in this volume. Firstly the political dimension, in the broad sense of the term, was no longer omnipresent as during the process of creation. Alongside it scientific and technical determinations were at work. The second consideration is that the institutional dimension was also inescapably present. Finally, there was no longer one dominant process in the organisation's life but several and it was no longer possible to tell just one story. The authors therefore decided to focus attention on various aspects of CERN's life.
Part I attempts to describe the various aspects which together constitute the history of CERN and aims to offer a synchronic panorama year by year account of CERN's many activities. Part II deals primarily with technological achievements and scientific results and it includes the most technical chapters in the volume, chapters using as main sources publications in the open literature, internal reports, and minutes of specialized committees or of divisional meetings. Part III aims to define how the CERN system'' functioned, how this science-based organization worked, how it chose, planned and concretely realized its experimental programme on the shop-floor and how it identified the equipment it would need in the long term and organized its relations with the outside world, notably the political world. The concluding Part IV aims to bring out the specificity of CERN, to identify the ways in which it differed from other big science laboratories in the 1950's and 1960's, and to try to understand where its uniqueness and originality lay.

Describing the history of CERN from its inception in the late 40's up to the mid-60's. The authors have divided these 17-18 years into roughly two successive periods. Volume I deals with the birth and official establishment of the organization and thus covers the years 1949-1954, while Volume II studies the life of the European laboratory during the first twelve years of its existence.
