In order to give you a little background information on the life and experiences of George Orwell I highly suggest you take a look at some of his earlier works. With a background touching everything from the Spanish Civil War to working in Burma with the Imperial Police, his colored experiences led him to become one of the most feared, inspirational and revolutionary authors of an era.
Here you can find some information about the critical essays he wrote for the Socialist Weekly Tribune, as well as some information about the publication itself.
The experiences in Homage to Catalonia which came out in 1938 explore Orwell’s development as a socialist and his objections to totalitarianism. You can place a hold on the item here with the Salinas Public Library, or here online with Project Gutenberg for a free full online copy of the text.
