An Arderin is also a descriptive word for a specific category of Irish mountains in the series of lists maintained by Mountainviews.ie; those over 500m with a prominence of at least 30m. This list, along with other complementary ones, has been published in book form by Collins Press. Mountainviews.ie classifies a mountain as being above 500m, but also maintains a number of lists of hills below this threshold.
