The Shapcott press was on the lower ground floor of Main Library. During the extension to Main Library there was discussion that the printery could be housed on the bottom floor of the Main Building. This last plan seems to reflect that idea. When Main Library was extended the Printery was moved to the Industrial Centre Building, located on the corner of Services Road and Hood Street.
