Between August 1884 and December 1909 Lawrence Hargrave read several dozen papers and presented a number of mechanical/aeronautical devices before the Royal Society of New South Wales. The papers, often profusely illustrated, were subsequentially published in the Society's Journal of Proceedings

The papers listed below, are linked to scans of the original journals from the archives of the Hargrave Library at Monash University or, in some cases, transcripts on the Australian Kite Association website.

The papers presented here deal specifically with Hargrave's work in aviation. Some half dozen papers relating to his work in non-aviation engineering and archeological research are not included as they are outside the brief of this website.

The posting of these papers on the web is a large task involving the careful scanning of documents in most cases over 100 years old, the digital repairing of defects and finally the scripting of pages to hold the scans.

Initially the focus will be on the latter period of his work. Please scroll down to view those currently available. The presentation date is in boldface, volume and page numbers where currently unknown, are represented by Volume 00, pp. 000-00
