R.L. Trask, The Penguin Guide to Punctuation (Penguin Reference Books)

R.L. Trask's The Penguin Guide to Punctuation helped me tremendously with the basic understanding of punctuation. Very easy to understand. - ideal for the beginner. Should be made available to all school children. I must point out that until I read this guide I was totally ignorant in regard to punctuation - I am still learning.

I was very impressed by the way most aspects of punctuation were explained. A very practical and easy to understand guide for both the young and mature student.
