I found the following item on the Limerick City Archives
Geary's Biscuit Factory, 1908-1982 ([url=http://la.cslhost.com/archon/findingaid.php?id=160&nostyle=1"]Link[/url])
Reference Code: IE LA P11
Scope & Content:
The series of photographs, provides a clear insight into the physical layout of the building in its former role- as a jail, with some shots also of the manufacturing enterprise that occupied the building for the majority of the twentieth century- large scale machinery. The photographic survey also includes some interesting wall sketches- probably drawn by the Geary children in the 1920's.
The collection also holds a series of letter books which provide a clear insight into the daily management of the business as well as the general climate in which industry operated in Ireland, notably the difficulty of receiving supplies from England during the First World War, the fear of arson and attack during the War of Independence as well as the challenge of delivering supplies throughout the war of independence when ambushes and requisitioning were commonplace. The collection also includes a large volume of account books that illustrate the daily transactions, purchasing of equipment, raw material and the changing financial climate. The collection includes a large number of wages books listing the large number of people that found employment in Limerick with Geary's.
According to the City Council site, viewing is "by appointment
", so you'll have to get in touch with them if you want to see the hard copy.
