Essential SharePoint 2010 Overview, Governance, and Planning by Jamison, Scott, Hanley, Susan, Cardarelli, Mauro. Published by Addison Wesley,2010, Paperback
This book gives a good overview of Administrative considerations for a SharePoint 2010 deployment. I found it particularly useful in thinking about an approach to designing site topology and governance rules, which was why I bought the book in the first place. Not the place to go if you want all the technical details, but great for thinking about planning a deployment.
