I bought this book to try to understand something of the Stone topology. Although this sounds like an obscure subject, the Stone topology is a way of giving a well understood limit structure to set algebras (and thus to algebraic structures in analysis), which is a very rich area. I confess though that I could not get on with this book. The category theoretic approach employed left me cold, and I was not sure of the value of the results achieved. I keep Stone spaces on my book shelf for reference, but I could not in truth recommend it for any other purpose. Of course it could simply be too deep for me ...
