A useful resource for finding old materials which are in print is Project Gutenberg. This mammoth project is dedicates to converting books into electronic text (or E-text. Contents range from the American Constitution to Alice in Wonderland. Project Gutenberg E-books can be downloaded from a number of sites. They are in a very basic ASCII format so that thay can be read by any type of computer. I found works by Robert W. Service and Banjo Paterson there. For the more adventurous there are works by Plato, Karl Marks and Edgar Rice Burroughs (the original Tarzan novels are very readable). The home page can be found here Project Gutenberg.
It is an excelent place to do various types of research as long as the material is out of copyright.
Good reading.
