That reminded me of a book I purchased recently called
Eats, Shoots & Leaves. When I purchased the book, I must admit that, even after some months of abstinence from this place, I thought that buying and reading this title might appease the "master of grammar" himself!
I've not read it all (yet) but it's written by someone whose intolerance of bad punctuation has become a self-obsession and makes for an amusing read.
My punctuation has improved a little from reading it but, since the book concentrates more on the "wrongs" rather than the "rights", it's hard to use as a guide to better grammar (not that that's what it's meant to be).
So, suggestions on easily-digestible books on punctuating me inglish betta wood be much appreciated guvnor.
