Part of the Australian National University Library
The Noel Butlin Archives Centre (NBAC) collects business and labour records from Australian companies, trade unions, industry bodies and professional organisations. They are a national organisation interested in material from all states and territories. The NBAC holds the records of large companies such as the Australian Agricultural Company, Burns Philip, CSR Ltd, Dalgety's,Tooth and Company and the Adelaide Steamship Company as well as those of smaller businesses such as pastoral stations. They hold records of federally registered trade unions and their predecessors, and of peak councils such as the Australian Council of Trade Unions (ACTU) and the National Farmers Federation. The records date from the 1820s to the early 21st century and include files, photographs, minutes of meetings, some staff and membership records, maps and plans, and publications such as trade journals and union newsletters. Some material may be closed because it is very recent or the owners' permission may be required before it can be used.
