The 1905 edition of Wise's Western Australia Post Office Directory is divided into three main sections: Towns, Alphabetical and Trades and Professions. These three classifications enable the enquirer to see at a glance the Householders or Traders in any one Town; the Business and Address of any resident in the State; and the
Firms throughout Western Australia engaged in any trade or profession.
THE TOWNS SECTION contains the usual separate Streets Directories of Perth and Suburbs, Fremantle and Suburbs, Kalgoorlie, Boulder and Coolgardie, with Alphabetical Directories of every other Town, Township and Postal District in Western Australia.
THE ALPHABETICAL SECTION contains the Names, Occupations and Postal Addresses for the entire State.
THE TRADES SECTION shows the Business Firms of the State, arranged under their trades or professions.
Separate directories are given in the following areas, making the work comprehensive and complete.
Medical, Ecclesiastical, Legal, Educational, Banking and Finance, Insurance, Mining, Pastoral and Agricultural, Local and General Government, Public Companies, Customs, Postal and Telegraphic.
The directory includes many pages of advertisements - all useful information, often including names of people and places.
The whole 1010 page directory, including most text in the ads, is searchable, useful not only for finding names, but also places, occupations and other information for family and local historians.
