External Reference Samples for Residual Stress Analysis by X-Ray Diffraction

International audienceThe GFAC (French Association for residual stress analysis) has been working for several years on external reference samples in relation with the EN 15305-2009 standard. The purpose of this campaign is to provide an external reference sample to each laboratory involved in the round-robin to allow a good calibration, a good quality control of their X-ray diffraction system and an easiest way to compare results between laboratories. All the procedures to qualify external reference materials will be described in the paper

The Institute of Archaeology Library 1937–1986: Collections, Communities and Networks

This article documents the history of the Institute of Archaeology Library from its independent beginnings in 1937 until the merger of the Institute with UCL in 1986. Documents from the Institute of Archaeology Library Archive, unpublished Institute Management Committee Minutes and published Annual Reports are used to demonstrate how the Library and the activities of its librarians reflected changes and developments not only in the Institute community, but also within wider archaeological networks. Initially situated in a united archaeological community with fluid boundaries, the Library was to develop its own independent identity as changes in Higher Education, professionalisation and commercialisation destroyed this unity and promoted the development of distinct communities of professional practice
