A number of books have been published about writing family history, a topic becoming increasingly popular with older Australians. Two titles I have recently looked at include Writing family history made very easy: a beginner's guide by Noeline Kyle and Writing your family history: a guide for family historians by Gill Blanchard.
Chapters in Noeline Kyle's book include Becoming a writer, Research and writing go together, Who are you writing for? Asking questions and finding ideas, Characters, Nostalgia, Historical context is what? as well as chapters on publishing your work. This Australian book provides useful clues to writing and publishing your family story. The section on publishing concentrates on producing a print publication which is probably not surprising as the text was completed in 2006. It is still, however a useful guide with ideas to consider when writing a family history.
British author, Gill Blanchard, published her book in December 2014. Chapters include Who, what, where, when, why and how, What kind of ancestral story, When to stop researching, Developing writing skills, Make it interesting - 'bringing the past to life', The nitty-gritty - from editing, proofreading and acknowledgements to copyright and Publishing. Useful tips and exercises are included in each chapter making this a practical step-by-step guide which is easy to follow. The section on publishing includes publishing online as well as publishing in book form.
Both of these authors have published family histories as well as other material on writing family history. A Google search provides additional information about the authors and their publications.
I also found this link to lecture notes by Noeline Kyle on the topic.
