Below is the first half of a list of Sigrid Undset's articles and essays as published by Aschehoug and edited by Liv Biksrud. These appear through four volumes (Essays og Artikler), each spanning a decade. What might seem a rather boring post to you I expect will be a hand reference to me, and forced me to at least translate the titles! It is interesting to note the list begins with impressions of Rome, but leads to Roman (Catholic) polemics from the time of her conversion (1924).

Are there English translations of these? Or at least some? It's so hard to find any of Undset's essays in English, but they are incredible!
