@icarus, what kind of websites has Netflix done with it's big flagship projects in the past? 

@fantasia - none as far as I'm aware! I can probably look into it, but I think that Netflix's strategy in the online domain is that the only website they want you going to is Netflix itself.

Perhaps that's part of the reason why they add placeholder slides for upcoming content to their site and app a year or so ahead of time.... Though that's another area that I can't seem to decipher much rhyme or reason behind why and when they do it.

Thought I'd check on this today.

'narnia.com' took me to an option to use the UK/Aus version of the site, but I chose to go on to the USA version.
This opened up:
https://www.harpercollins.com/pages/narnia

It has the new book covers, the existing box sets, individual books, the original paperbacks from 1970s (box and individuals), then the audio books, and finally the two books for young children.

Going back to the UK version: 
https://harpercollins.co.uk/pages/narnia

The books are listed starting with the box sets, then a set of 'Original books' with Baynes illustrations on bright background colours, then the new covers. then the classic editions in full colour, then audio books, then young children's ones.

The main difference is in the order.
