Timeless Advice
I'm not a journalist by trade, but I admire the journalistic approach to writing. It's about cutting out the fluff and getting to the point. Anyone who writes can benefit from Robert M. Knight's book. Mr. Knight writes with an authoritative and sometimes humorous voice. The section on usage is a gold mine of clarity. As an added bonus, you get a section on the evolution of English. This book has now become one of my go-to references. I highly recommend it.
