General History of Australian Bushrangers (Online Book)
http://gutenberg.net.au/ebooks12/1201551h.html
This is part of the Project Gutenberg Australia effort to provide access to books with expired copyright and on the public domain on the Internet. Its copyright has expired because of its age, with it first being published back in 1898. Consequently, it is perhaps a bit dated, but it does include an extensive selection of contemporary primary resources and does provide detailed accounts of the various Australian bushrangers.
