Books on the Australian Flying Corps
Australian copyright allows for a published book to be protected under copyright law for 35 years after initial publication. After that period, the book becomes public domain in order to preserve the cultural addition the publication made. Several books published in Australia on the Australian Flying Corps are now public domain. Books such as "The Battle Below" were published in 1935 in a short run and are now expensive to procure as second hand books due to their rarity.
The Battle Below
"The Battle Below. Being the History of No.3 Squadron A.F.C." was authored by H.N. Wrigley, previously the Commanding Officer for 3 Sqn and was published in 1935 by Errol G. Knox, Warwick Building, Hamilton Street, Sydney.
