This collection consists of technical books, papers, and manuscripts documenting the history of the electrification of Grand Manan. The ledger documents the installation of wires to individual locations and then maintenance at that location. The ledger used was a telegraph ledger but the entries are all for 'Electrical Works'. The ledger was used from Oct. 1929 to 31 Jan. 1930. Also included is an NB Power Museum Kit, acquired in 1990, which contains a history of the electrification of the Province of New Brunswick. There is also an NB Power calendar for 1994.
