Library and Archives Canada has made available online four volumes of records about Kingston Penitentiary inmates (link in Resources below). Most of the records date from about 1912 to 1919, with a small number of earlier or later records.

Each page includes a pair of photographs (mug shots), a physical description of the inmate, date and place of sentencing, and the crime for which he was convicted. In some cases, a newspaper clipping about the crime has been pasted into the ledger.  The inmates' names are searchable on the LAC website or in the index found below.
