These volumes were apparently commenced about 1834 in Launceston, and entries before that are made retrospectively
there are often discrepancies between the details given here and those in the conduct registers (CON31), and it appears that the earlier particulars were copied from some other source known as "the original Black Books"
sometimes, for example, earlier and later offences are recorded here, and sometimes offences recorded in the conduct records do not appear here.
The details given include number, name, ship, original sentence and offences (with particulars of sentence and magistrate) and both men and women are included.
These records are part of the holdings of the Tasmanian Archives
