A comprehensive compendium of both current and historical acronyms and abbreviations used in the context of European Union RTD has just been published by CORDIS. Containing over 4,900 entries taken from the RTD-ACRONYMS data base, "European Union R&D Acronyms" is an indispensable desk companion for those with an interest in European Union research activities but who sometimes find themselves bowled over by the myriad of acronyms used. More than just a list of acronyms, the publication provides supplementary information on each entry including, where appropriate, a short informative summary, the responsible Commission service or other originating body, and links to Commission programmes. The bulk of the content of "European Union R&D Acronyms" is made up of over 3,600 acronyms designating Commission-funded projects, with some 400 entries describing Commission-funded research programmes (Full details of these projects and programmes are available on the CORDIS RTD-PROJECTS and RTD-PROGRAMMES data bases respectively). Other categories of acronym (organizations, committees, facilities, etc.) are obtained from a variety of sources, including official documentation, publications and active information collection from RTD programme officers. A small number of entries, which are of relevance to, though not strictly speaking within the scope of, RTD and technology transfer activities are also listed. Acronyms originating from activities which are not directly sponsored by the EU may also be included if they relate to EU RTD activities. "European Union R&D Acronyms" is not, however, intended as a comprehensive guide to non-EU acronyms. Acronyms have become a major feature of R&D, serving often to reduce complex and long-winded terminology into snappy, easy to use, buzzwords. So instead of being left wondering about the meaning of "the implementation of the FEVER project under JOULE", "collaboration between the JRC and the ESA in the creation of the EEOS", or the thousands of other frequently used RTD-related acronyms, make sure you have a copy of "European Union R&D Acronyms" at hand.
