This page contains links to the Church of England report of this name.
It is a 'rare document' but can be found in some Church libraries and for sale on line.
I found out about it from Archbishop Justin Welby himself, on the following video (he mentions it about 23 minutes in) http://youtu.be/6dvkBdXLx3A
I have compiled a contents list for the report which is available below to download as a series of PDFs
I suggest you start with the 'Overview and Contents List', which also gives Copyright information
