I've noticed recently that some CZ articles have evolved from one into two and thence to several. Fora time there, the main article on Contraception had only a single section ("Christian views on contraception"), and one of the two ridirects at the top of that entry led to another main entry with the same title and content as this subsection! Most recently I happened to look up Joan of Arc, to discover that we have:
Joan of Arc
Joan of Arc, memory of
Joan of Arc, Rehabilitation trial
Joan of Arc, timeline
Joan of Arc, Trial
I can't for the life of me imagine why all of these things oughtn't to be in a single aricle, Joan of Arc. Wouldn't someone looking at her trial appreciate a timeline? And as for "memory of," this seems impossibly vague (does this reference Joan's own faculty of memory, the accounts given of her life from memory by others, or just the general historical reception of Joan's life over the centuries?
I fear we are skirting toward the infamous encyclopedia described by Jorge Luis Borges, which offered the following as its main sub-categories under the main entry "Animals":
(a) those belonging to the emperor
(b) those that are embalmed
(c) those that are domesticated
(d) the suckling pigs
(e) the sirens
(f) fabulous ones
(g) the roaming dogs
(h) those included in the present classification
(i) those that drive themselves crazy
(j) innumerable ones
(k) those painted with a very fine brush of camel hair
(l) et cetera
(m) those who have just broken the jug
(n) those who resemble flies from afar
Well --maybe it's not yet *that* bad.

But I would propose that the Editorial Council, or someone, add some guidance on this -- when (generally) sub-articles are appropriate, who should decide if there is any doubt, and some sort of process by which this decision could be ratified such that constables could enforce it. Maybe such a policy could be called "Article Propagation"?
