The State Library of Queensland has just re-released the British Convict Transportation Registers Database (over 123,000 convicts sent to Australia between 1787 and 1867).
A new feature of the database is the ability for researchers to post comments on a chosen convict's record. This comment field is a great way for researchers to share their notes on a convict's life.
