I'm afraid I don't, not at hand, but one phenomenon I've noticed and am going to make a point of documenting the next time it occurs is that there is a significant tendency for references to be lost over time.
Hopefully the new cite.php reference formatting will help in this regard. Reference text can now be bundled directly with the text that it is a reference for with the list of references at the bottom of the page being automatically compiled from that. It makes it impossible to have "orphan references" now, and perhaps having the full description of the referenced material in place will make it harder for an editor to accidentally delete it when removing unrelated material.
