Lasers continue to be an amazingly robust field of activity. Anyone seeking a photon source is now confronted with an enormous number of possible lasers and laser wavelengths to choose from, but no single, comprehensive source to help them make that choice. The Handbook of Lasers provides an authoritative compilation of lasers, their properties, and original references in a readily accessible form. Organized by lasing media-solids, liquids, and gases-each section is subdivided into distinct laser types. Each type carries a brief description, followed by tables listing the lasing element or medium, host, lasing transition and wavelength, operating properties, primary literature citations, and, for broadband lasers, reported tuning ranges. The importance and value of the Handbook of Lasers cannot be overstated. Serving as both an archive and as an indicator of emerging trends, it reflects the state of knowledge and development in the field, provides a rapid means of obtaining reference data, and offers a pathway to the literature. It contains data useful for comparison with predictions and for developing models of processes, and may reveal fundamental inconsistencies or conflicts in the data.

The crannog on Llangorse Lake near Brecon in mid Wales was discovered in 1867 and first excavated in 1869 by two local antiquaries, Edgar and Henry Dumbleton, who published their findings over the next four years. In 1988 dendrochronological dates from submerged palisade planks established its construction in the ninth century, and a combined off- and on-shore investigation of the site was started as a joint project between Cardiff University and Amgueddfa Cymru - National Museum Wales. The subsequent surveys and excavation (1989-1994, 2004) resulted in the recovery of a remarkable time capsule of life in the late ninth and tenth century, on the only crannog yet identified in Wales. This publication re-examines the early investigations, describes in detail the anatomy of the crannog mound and its construction, and the material culture found. The crannog’s treasures include early medieval secular and religious metalwork, evidence for manufacture, the largest depository of early medieval carpentry in Wales and a remarkable richly embroidered silk and linen textile which is fully analysed and placed in context. The crannog’s place in Welsh history is explored, as a royal llys (‘court’) within the kingdom of Brycheiniog. Historical record indicates the site was destroyed in 916 by Aethelflaed, the Mercian queen, in the course of the Viking wars of the early tenth century. The subsequent significance of the crannog in local traditions and its post-medieval occupation during a riotous dispute in the reign Elizabeth I are also discussed. Two logboats from the vicinity of the crannog are analysed, and a replica described. The cultural affinities of the crannog and its material culture is assessed, as are their relationship to origin myths for the kingdom, and to probable links with early medieval Ireland. The folk tales associated with the lake are explored, in a book that brings together archaeology, history, myths and legends, underwater and terrestrial archaeology.

Pioneering work on the musical material from the archives of the English court was undertaken by Nagel (1894), Lafontaine (1909) and Stokes (in the Musical Antiquary 1903-1913). Records of English Court Music (a series of seven volumes covering the period 1485-1714) is the first attempt to compile a systematic calendar of such references. It aims to revise these earlier studies where necessary, adding significant details which researchers omitted, clarifying the context of documents and substituting current call-marks for defunct references. Volume V is primarily concerned with the post-Restoration years already partially covered in volumes I and II. The material from the Exchequer and Declared Accounts of the Treasurer of the Chamber has been revised to include references to trumpeters and drummers. Other sections are devoted to material outside the Lord Chamberlain's papers: the Signet Office Docquet Books, Secret Service accounts and more from the Exchequer; the Corporation of Musick (controlled by the Court musicians) and to the range of music material from accounts of the Receivers General. Samples from the comprehensive records of the Lord Steward's department (including those of the Cofferer of the Household) are also provided. Andrew Ashbee was the winner of the Oldman Prize in 1987 for Volume II in the series of 'Records of English Court Music', awarded by the UK branch of the International Association of Music Libraries for the year's best book on music librarianship, bibliography and reference.
