In computer science and mathematics, a sorting algorithm is an algorithm that puts elements of a list in a certain order. The most-used orders are numerical order and lexicographical order. In Google Sites, we can insert a Subpage Listing gadget, when we choose "Show sub-pages of: the current page", and "Show levels: All", this gadget will list all subpages under the current page in an order. The problem is that the listing will automatically be sorted in lexicographical order. Now I have a book that its chapters use Roman Numbers, in the subpage listing chapter IX is put after chapter IV instead of chapter VIII: BOOK I. Enjoyment in Untroubled Ease BOOK II. The Adjustment of Controversies BOOK III. Nourishing the Lord of Life BOOK IV. Man in the World BOOK IX. Horses's Hoofs BOOK V. The Seal of Virtue Complete BOOK VI. The Great and Most Honoured Master BOOK VII. The Normal Course for Rulers and Kings BOOK VIII. Webbed Toes
