Paris, 22±23 March, 1999 The meeting report of the IAG EC meeting was published in the previous IAG newsletter (JG7305). Minor corrections have been received and the corrected minutes can be found at the IAG internet site at http:/www.gfy.ku.dk/iag/ec9903.html Fast Bibliography The fast bibliography consists of a listing of papers relevant to Geodesy that has been collected by the IAG bibliographic service since the previous issue of the fast bibliography (JG73/04). The IAG bibliographic service is based on the literary data bank GEOPHOKA, which is maintained by IfAG at the Branch Oce Leipzig, Leipzig Zentrale technisch± wissenschaftliche Angelegenheiten, Bibliothek, Karl± Rothe±Strasse 10±14, 04105 Leipzig, Germany This version of the fast bibliography has been supplemented with papers registered by Tables of Content in Geodesy provided by M&M Craymer and with papers registered by the American Congress on Surveying and Mapping (ACSM) bibliographic service.
