I should have said that the exhibition about Maurice Dorfman is in Clapham Public Library, conveniently close to Clapham High Street station which is on the Orange Line (I travelled straight back to Whitechapel) and Clapham North which is on the Northern Line (but remember that the Moorgate branch is partly closed), and part of the pleasure of the exhibition is the way it is laid out through the library, which, whatever its defects as a library, works well as a space for exploration. Also, the exhibition was originally going to close at the end of this week, but has now been extended to May 28th. If it wasn’t already obvious, I strongly recommend it and attach a) a piece in the Guardian about it:-
And, b) the website address of the exhibition which tells you how to buy the book:-
