This is an excellent guide to article writing and is equally appropriate for lengthier research work.It can be adapted to chapter writing for example. It is based on a 12-week course but could be done in a shorter time depending on one's personal experience, style ,etc.It is well-rooted in the experiences of a wide number of peoople so is not just one person's views, despite the authorship. There are many relevant examples. What I particularly liked about it was that it is realistic about an individual's motivation, (or lack of it!) reluctance to write more than 20 minutes a day, and so on.
I thoroughly recommend it.
