As a result of the growth of trade and commerce that accompanied the Industrial Revolution, ships grew in size necessitating artificial enlargement and deepening of harbours.

In many cases this was done through local Acts by which trustees or commissioners were incorporated to build or improve and manage docks and harbours.  Many records relating to these harbours are scattered through our holdings but listed below are principal collections:
