Look to Windward original title
I thought I'd share a wee bit of information I picked up the other day, that I've not seen elsewhere on the internet.
I've purchased prints of a couple of Culture novel covers from the artist, Mark Salwowski.
(https://www.salwowski.com if you're interested. He also is selling the original artwork for other author's books.)
One was for the cover for Look to Windward, which he has listed with the title 'Peer Group'.
I asked why the alternate name. He responded
"... the working title of ‘Look to Windward’ was ‘Peer Group,’ and the manuscript I worked from was labelled as such. I believe there was some kind of tiny test print run for promotional purposes that had the title too."
I can imagine Banks maybe wanted to obscure the background of this book until release time. The final title clearly tells readers it is related to Consider Phlebas.
The particularly interesting bit is that note about the tiny preproduction run with the working title... which must be in someone's collection, somewhere...
