I find Della Galton's book a very useful and highly informative read. It's well-presented and easy to dip into. Her advice is not only about the 'creative and literary' aspects of writing short stories for magazines but also covers practical items e.g.tax and keeping track of your stories.
I also like the fact that she includes advice and tips from other professional writers, who like Della, are well-known and experienced in their field.
I would definitely recommend this book, both to complete novices and to those like myself, who are already a little way along 'the write road'.
