The school archive is housed in the Bob Booth Archive Room. It comprises documents, photographs and artefacts relating to the founding of the school in 1911 and its history. Sydney Tech spans three educational sites; Ultimo; Paddington and Bexley, and information relating to alumni, past teachers and the life of the school can be readily found in the archives.
The archive contains the most complete set of research files relating to Sir Charles Kingsford Smith, an Old Boy of the school, in Australia. The research files were most recently used by Peter FitzSimons for his book on Kingsford Smith, "Charles Kingsford Smith and Those Magnificent Men", published in 2010.
In 2011 the archive was renovated for the school Centenary Celebrations and was extensively used by Dr John Morrison in his book "The Story and Times of Sydney Technical High School, 1911-2011", published in 2011 to celebrate one hundred years of school history.
In 2022 the archive was relocated into one of the cottages on site. Alumni can access the school archives on Wednesday afternoons by appointment only. Please phone the school on (02) 8566 2600 to arrange.
