1.01 This section provides a numerical listing of all indexes released as Bell System Practices and the subjects(s) covered by each. 1.02 A bullet lei indicates an item that has been added or changed since the previous issue of the index. 1.03 A square () indicates () canceled item. Information relating to the cancellation, if necessary, will be shown in a note following the item. Canceled items and related notes will be deleted upon reissue of the index. 1.04 If the number shown below ends in -000-000, it is the numerical index for that division. Any other number indicates an index such as alphabetical, permuted, interdivisional, etc.
