Contagious Curiosity : Smart Business Intelligence Solutions with Microsoft SQL Server 2008: Lynn Langit
Check out this great book that my geekSpeak colleague Lynn has just wrapped up. She went through a lot of ups and downs writing this book, and I think the process is similar to what they say about sausage - you like the end product but you don't want to see it being made. In any case, congratulations to Lynn and I'm sure that this book will be the de facto resource for learning about BI in SQL Server 2008.
