Literature Resource Center is an excellent online resource for this work and its author. Just fill in "to helen" in the Title of Work box and "poe" in the Person by or about box.
Another good source for articles on Poe's "To Helen" is JSTOR. Do the following search in this database: "to helen" and poe.
