How would I do that now? Wikisource pages are not structured data (though Wikimedia Commons image metadata will soon be!), so there is not a clear way to use the Wikisource API to extract just the relevant transcribed text on the page as a field. And on top of that, any text you do extract this way will be full of templates and other code that has no meaning outside of the context of Wikisource. I don't see a way to easily extract just the plain text that is meaningful and relevant (along with other fielded data, like what page or text it belongs to).
