I've been blogging about sorting for a while:
There's just one more thing to mention: creating your own custom sort order.
Existing sort orders are things like Monday Tuesday Wednesday (the right order, which is not alphabetical). But let's say you've got things you want in a certain logical but non-alphabetical order that aren't already set up in OpenOffice.org: titles of books or people, procedures done in a certain order, or your own abbreviations for the days of the week. You can create sort orders for those very easily so you can sort by them.
