These URLs were helpful to me when constructing my presentation:

http://en.wikipedia.org/wiki/William_Wordsworth - The Wikipedia article on the author, a great help when looking up Wordsworth's life.

http://librivox.org/i-wandered-lonely-as-a-cloud-by-william-wordsworth/ - This site is a giant audio library containing thousands of books and poems read aloud by various contributors. It is also public domain, and thus doesn't require any permission or citing to be used.

http://en.wikipedia.org/wiki/I_Wandered_Lonely_as_a_Cloud - This wikipedia article is about the poem itself, and not only was my source for the poem text but also had a short analysis of the poem.
