Singing praises

I just want to say how much I am enjoying reading this book: Robert Rauschenberg Breaking Boundaries by Robert S. Mattison, published by Yale .  It is one of those extraordinary texts which really tells you so much about the work of an artist.  I find it like being in Rauschenberg's studio while he works.
Mattison takes five bodies of work by Rauschenberg and examines them in intimate detail: the making, the meaning, the influences, .... There are photographs illustrating what is discussed, but this is primarily a book full of fascinating text.  It was written with Rauschenberg's co-operation, and was published when he was alive.
For someone like me, constantly asking questions about artistic expression in my own work as well as that of established artists, it is a treasure chest.  It starts with a description of Rauschenberg's purpose built studio and how it functions, so is very much concerned with how he made art as well as why. 
I am finding it brilliant, it makes me feel really great - and to think I stumbled across it in Amazon when I was looking for something else to do with printmaking!   Now I just want to shout about it.
