Critique "Auguries of Innocence"

Hi. I'm working on an analysis eassy of a poem's diction and imagery. I have chosen Williams Blake's "Auguries of Innocence", but I cannot seem to find any scholalry critiques on this poem. I am supposed to use a few quotes from respected journals in order to help my arguement. If anyone has a suggestion as to where I can look, I would greatly appreciate it

P.S. I am ultimately supposed to derive the theme of the poem, it would be great to hear your opinions on the poems theme.

Thanks...
