Sources
- Beaver Beacon, February 1961, “Island news.”Publishes a directory of new island telephone numbers following the January switchboard report. The directory is preserved as source material without repeating private residential numbers in the KB; it does not provide subscriber contracts, switching records, or a complete historical numbering plan.
- Beaver Beacon, May 1961, “BITCO News.”Reports five new telephone installations and names the subscribers, but the private numbers are intentionally not reproduced in the knowledge graph. It does not provide a complete directory or installation ledger.
