Ah yes, sorry Waista. Should have made myself clearer on that. I was ignoring the idea of creating a nomenclature to be included in the titles because it struck me as an incredibly bad and confusing idea. I have yet to come across a classification scheme based on numbers or letters that is easy to instantly understand and expand. I respect the FDO's ability in publishing novels, marketing and self promotion, but I think this is a bad idea.
Wasn't advocating putting this on the cover either, in the first few pages alongside, 'Also By the Same Author' type of thing. I've never seen anyone buy a book without leafing through it first.
