On the latest Lisa Louise Cooke Genealogy Gems podcast I learned that she has a new book on Google for genealogists, and that it's part of the growing self-publishing trend. It promises:
"Google Search: Put an end to fruitless searches forever Google Alerts: Your personal genealogy research assistant Gmail: Never loose another email iGoogle: Create a genealogy research dashboard Google Books: The world’s history at your fingertips Google News Timeline: Get the scoop on your ancestors Google Translate: Open the world of foreign language documents and websites YouTube Videos: Your family history in action Google Earth: Rock your ancestor’s world!"
Self publishing services offer print on demand with no expensive inventory to maintain. In this case you can purchase an online version as well as hard copy.
