I think it's encouraging to see that there is some interest in a project like this.
Firstly, I must point out that I am not a professional writer and I've personally never published anything more involved than a service engineers newsletter. That said, I know a few people (and now Peter too, of course) who could give help and guidance.
Two books precipitated this (I'm not claiming this as my idea - I merely hijacked someone else's idea on this thread). The first is called "A Day In The Life Of A Nation", which is a large format book full of colour DPS images of life in the USA all taken on one particular day. There is only minimal copy, basically describing when and where the shot was taken. It's a compelling album, which I found hard to put down ("A rip-roaring pot-boiler that has the reader spell-bound from first page to last" - Charlie Bloggs, Cleckhuddersfax Chronicle).
The second is another hardback, large format book called "The Long, Long Day" This is a photo-record of the 1986 24 Hour Race, produced by Nissan Motorsports Europe. Not sure if it was ever offered to the general public (I used to do some marketing work for Nissan and they gave me a copy). It is somewhat biased, in that it focusses on the two Nissamax Group C cars, that were pretty mediochre, but it is beautifully presented and very atmospheric. Again, it's light on copy, but a nice thing to browse.
I would be very keen to see images of both the race and the 'side-show' from the last 30 years or so - but I'm based in the USA - not UK, so mailing them could be troublesome and expensive. Is it possible to post onto a picture hosting site, so that editing could become a group effort? What I'd be looking for are images that tell a story, or are unusual or emotional. How do we progress this, I wonder?
