One volume p.o.
Is there a 1-volume book in publication order? I am searching on the internet but the only I can find, is volume in c.o.
Besides there are other editions except Har. Coll edition.
Αs there are no copyrights, why doesn't a publisher decide to print a volume in p.o?
I've never heard of one, but then I have to admit that I haven't looked too hard.
C.S. Lewis is only out of copyright in certain countries right now; Canada is one of them and Australia, I think. It'll be another thirteen years in the UK (well, fourteen really--beginning of 2034) because they have life +70 rules. Also, since the Chronicles are still in print and easily found for reasonable prices, at this point it may not be worth anyone's while to do an edition like that.

I think by the time the Chronicles started to be published in one-volume editions, the publishers had already decided that the chronological order was the "correct" order, so that's how all the one-volume editions are, as far as I know.
That's interesting that the Chronicles are out of copyright in Australia — I'm Australian (though I now live in Britain) and I didn't know that. I thought our law was "life + 70", which I just checked and it is, but it used to be "life + 50" until 2004 and the new law doesn't apply retroactively to anything published before then, which includes the Narnia books. However, they don't have a separate Australian publisher, so we've always had the British editions. I guess that means an Australian-based publisher COULD legally publish new editions, including a single volume in publication order, but as @aileth says, I don't think most publishers would be interested while the current British editions are still in print and easily available.
