This booklet is a compendium of those basic nuclear physics facilities world-wide which are considered genuine user facilities by management. As far as it has been possible the information is complete and accurate. However, the very nature of IUPAP means that participation is purely voluntary and in the case of a very small number of countries we have been unable to obtain information. In addition, apart from personal knowledge of the members of the committee it has been necessary to rely on the information provided by the facilities themselves. In spite of the obvious difficulties this is probably the most comprehensive summary of the research facilities available to the international nuclear physics community that has been compiled. It has been supplemented by a brief outline of how these facilities relate to what the committee feels are the major questions facing us in key areas of nuclear science.
