The library is located on the lowerground floor and contains books that once belonged to the Waite family and those collected during the early period of the Waite Institute.
The collection reflects Waite's great interest in new technology, including new inventions such as refrigeration and electricity.
The shelving and original tub chair in this room belonged to Peter Waite.
The desk is believed to be that of the first Director of the Waite Institute, Professor Richardson, who used the room as his office before the main buildings of the Institute were completed in the 1920s.
The Library is open during guided tours of Urrbrae House.
