You can research old photos in the the Lewisham local History Library, on the top floor of Lewisham Library, and you can order copies of them.
There are several books by John Coulter and others (John is a local historian) and the best one for HOP area is Forest Hill and Sydenham (Britain in Old Photographs) by J. Coulter and J.Seaman, Sutton Publishing Ltd 2003, ISBN 0-7509-2918-9.
This book has chapters on "Brockley Rise etc." and "Honor Oak Road etc".
It's a bit of a shock to see familiar roads without a single parked car!
