The problem with attempts to define 'traditional' by providing a list of what it encompasses is that the list is unlikely to be complete.

For example there may be (perhaps smaller or lesser known) collections other than those in the Captain's list, which might well have an equally good claim to be 'traditional', but are excluded simply because no-one thought to add them to the list. I'm not saying I know of any, but there's no reason why they shouldn't exist.
