LAYOUT OF VOLUMES I, II AND III (Recommendations, Reports, Resolutions, Questions and Study Programmes of the C.C.I.R.) General The Recommendations, Reports, Resolutions, Questions and Study Programmes of the C.C.I.R., the texts of which appear in Volumes I, II and III, are those which have been approved by the IXth Plenary Assembly of the C.C.I.R., together with those which, approved by the Vth, Vlth, Vllth and VUIth Plenary Assemblies, have been retained. The Recommendations, Reports and Resolutions of a general nature are arranged in numerical order. The Questions and Study Programmes are grouped together and arranged in the numerical order of the Study Groups. For each Study Group the Questions are laid out in numerical order, each being followed by the Resolution(s) and Study Programme(s) to which they are related. Study Programmes which are not the result of a Question are indicated by a note. Questions submitted to the C.C.I.T.T. form the subject of a separate chapter. References to the texts, if any, forming the basis of Recommendations, Reports, Resolutions, Questions and Study Programmes are given below the title. On the right under this reference is shown the Plenary Assembly or Assemblies which have approved or subsequently modified the text. Mention is made in a footnote, when the occasion arises, of the texts or text which have been replaced by the text in question; in the case of a Question, the Study Programmes are shown which arise from it; and in the case of Study Programmes, mention has been made where necessary of the Questions to which they refer.
