This series consists of notebooks used by Justice Sir Cyril Walsh during cases heard in Adelaide, Hobart, Melbourne, Sydney, Brisbane or Perth.

The notebooks are small 'exercise' books, each with consecutively   numbered pages, some with alphabetical indexes at the front.  Those notebooks without indexes incorporated in them have a handwritten index on the front.  These indexes referred to a particular case by the surname of either the plaintiff or defendant and include the page number in the notebook where the notes to the case were  written.

There are no references made to the case number, only the names of the plaintiff and defendant, so it may be necessary to peruse either  the South Australian Full Court Book (A10149), the Tasmanian Full Court Book (A10143), the Victorian Full Court Book (A10220), the New South Wales Court Book (A10232), the Queensland Full Court Book (A10041) or the Western Australian Full Court Book (A10080) around the date/s of the notebook entry to verify the case number before searching for the records of the case.
