> What's wrong with Public Domain books? The whole Western literary canon is in the public domain. You could spend as much time as you wanted purely on those books without ever needing to read anything proprietary or encumbered. There is much to be said for that, but tastes differ, and books aren't entirely fungible. If you really prefer reading science fiction and fantasy for example, you're going to run out of public domain and Creative Commons licensed works that appeal to you pretty quickly.
