Some stuff I've found so far...

Billington, Ray.  "Maria Monk and Her Influence."  The Catholic Historical Review 22.3 (1936):  283-96. JSTOR.  Web.  11 Sept. 2010.

Thanks, mom!

Wow, you can really tell from this guy's tone that he's writing in a Catholic publication.  He's pretty scathing about the Protestants and their propaganda (maybe with good reason, but still).  Also, given how early this was written, it's possible that not all of the controversy had died down yet and the Catholic church still had some residual pissed-offness about the whole thing.  Either way, this source gives a pretty useful summary of all the early reviews and interviews and discussions in Catholic and Protestant papers within the first couple years of Awful Disclosures's publication.  In particular, he mentions an interview with Maria Monk's mother in which case she says that Maria Monk was a wild kid and a crazy adult, was actually in a mental institution, not a convent, in Montreal, and that her baby was that of her lover and not a lascivious priest.  While this sounds more plausible than the convent story, I like to think that if I were to ever run into trouble my mom wouldn't throw me under the bus like that.  Thanks Mom.

Griffin, Susan.  "Awful Disclosures:  Women's Evidence in the Escaped Nun's Tale."  PMLA 111.1 (1996):  93-107.  JSTOR.  Web.  23 Sept. 2010.

Places Awful Disclosures in context of proliferation of escaped nun tales at the time; as it turns out, most of them (Awful Disclosures included) were hoaxes designed to create more anti-Catholic panic than there already was (because clearly there wasn't already enough mad religious fervor going on).  All the corroborating stuff (the exhaustive appendices, supporting articles, etc.) becomes a trope used in more or less all of these tales.

Mannard, Joseph.  "Maternity . . . of the Spirit":  Nuns and Domesticity in Antebellum America."  U. S. Catholic Historian 5.3/4 (1986):  305-24.  JSTOR.  Web.  11 Sept. 2010.

Argues that part of the reason Protestants were so against convents is that they kept women from being in their "proper place":  home, barefoot and pregnant.  Interestingly, Protestant men and women objected to convents for different reasons:  men because it was horrible and unnatural to keep women away from the great joys of male company and childbearing (ha!), women because they wanted alternatives:  Protestant schools and seminaries that admitted women, etc.

Pagliarini, Marie.  "The Pure American Woman and the Wicked Catholic Priest:  An Analysis of Anti-Catholic Literature in Antebellum America."  Religion and American Culture:  A Journal of Interpretation 9.1 (1999):  97-128.  JSTOR.  Web.  11 September 2010.

Similar to Mannard (although a little more thorough, and a lot more current), discusses anti-Catholic literature as largely stemming from Catholicism's undermining of the "cult of domesticity"; hence the stereotyping of Catholic priests as depraved sexual madmen and nuns as innocent, deceived victims.

Much, much more to come, but here's a start.
