I love e-books, it’s so embarrassing turning up on a client site with a pile of manuals (even worse if you are a Microsofty!), as they assume you have all of books on line (BOL) and the TechNet library stored in memory. An e-book allows you to be more discrete and saves you blowing your baggage allowance or doing your back in as go from site to site.
So here’s one for free form MS Press – Introducing Microsoft SQL Server 2008 by Peter DeBetta, Greg Low and Mark Whitehorn. To get follow this link.
My other tip is to pull down BOL from TechNet, so you have it to hand even if you haven’t got SQL installed on your won machine.
