I recently received from the National Library of Australia electronic versions of the letters William Denton sent to Alfred Deakin. When I initially asked about the letters I was told that item 1/11 was missing though there seems to be two lost letters. The first letter 1/11 is absent or perhaps never existed as noted by the file image but item 1/15 is also does not have a document associated with it though it has not explicitly identified as being a lost file. It is not the first time that I have come across astray archives.
Late last year when I was attempting to find more information about the Melbourne Argus expedition in New Guinea on which Denton died I was told by a librarian at the State Library of Victoria that the whereabouts of the Argus administrative archive are unknown. So while copies of the newspaper have been digitised all other documents that the newspaper might have had, like correspondence, are lost or even destroyed.
