Well, in the USA my book, The Great Big Book of Baby Names, is at this time only available through an outfit called Quality Books, Inc., that only sells to libraries. (Feel free to suggest to your local library that they purchase it!)
But I have just discovered that there seems to be a mail order book place called Nationwide Books in New Zealand that is now carrying it! So if you live in New Zealand, you can purchase the book as a private citizen.
Here's the URL:http://www.nationwidebooks.co.nz/index.cfm/Reference.html
I see that in New Zealand the book costs $29.99 NZD. Does anyone know how that would translate into US dollars?
