Source: Document 6/62

Documents ITU-R 6/395 and 6A/73 outline the need for indexing on the ITU R website to provide user-friendly information that would allow browsers to easily identify those Recommendations that cover their areas of interest. Document ITU-R 6R/3 provides an example of categorizing and summarizing Recommendations. Working Party 6A has prepared the proposed “Guide to ITU-R Recommendations under the Responsibility of Working Party 6A” as shown in the Annex. The guide includes categorization and a brief description for each Recommendation plus several charts showing the relationship among Recommendations covering similar topics.
