Wiedemann has published poems in a number of journals, including Kaleidoscope, Kerf, Poetry Motel, and Acorn. Most recently, a collection of her poetry entitled Half-Life of Love was published by Finishing Line Press.

Wiedemann has authored a critical study, Josephine Herbst’s Short Fiction: A Window to Her Life and Times, on the work of Josephine Herbst, the radical American writer, and is the co-editor of two books, Short Fiction: A Critical Companion and "My Name Was Martha": A Renaissance Woman's Autobiographical Poem. The latter is the first edition of a 1632 autobiographical poem, 110 lines long, by a woman called Martha Moulsworth--one of the first such poems in English, which was included in the seventh edition of the Norton Anthology of English Literature.

Her essay on Hélène Cixous and Marguerite Duras, "The Search for an Authentic Voice: Hélène Cixous and Marguerite Duras," was reprinted in the collection Marguerite Duras Lives On.
