Just received my copy of Microsoft SharePoint: Building Office 2003 Solutions by Scot P. Hillier.
On first glance, this looks like a great book for anybody needing to get up to speed on SharePoint quickly. Hillier breaks all of the various concepts - from configuring SharePoint to doing custom development - into logical chapters. He describes the concepts well, and then provides exercises to demonstrate each concept. This is great for folks like me who are looking to get the functionality up and running in a short time.
Hillier even discusses a few of the Solution Accelerators. He describes and demonstrates the Proposal Accelerator, which Quilogy help build. He also describes and demonstrates the Accelerator for Recruiting which I had the pleasure of helping to build and test for Microsoft.
Overall, a well written and organized book. Highly recommended.
