abstract: The article "Reagan seeks expansion of Soviet ties" by R. Jeffrey Smith (News and Comment, 13 July, p. 145) erroneously stated that the U.S. Senate had passed a resolution calling for a U.S.-Soviet summit "without preconditions or assurances of success." Shortly before midnight on 19 June, the resolution was amended to call for a summit at "the earliest practical time following thorough preparation." It was approved in this form.
