Online archive of the 1898-9 Booth Poverty Map

I have been using the Charles Booth Online Archive recently, which is a terrific resource for finding out what sort of housing existed in all parts of London at the turn of the Victorian century.  The Southwark page includes the parishes of Holy Trinity, St Mary's, St Barnabas, All Saints and Christchurch.  A key is provided on each page so that you can see what the colour coding on the map means. A particularly useful feature is the ability to compare Booth's original map with a modern map on the same page at the same time.  The screen grab below shows the parish of Christchurch.
