What are some recommendations for books, when talking strictly about programming against the Object Model API for SharePoint 2007?

Question

I've read quite few books regarding programming for SharePoint 2007, but in reading these books*, and referencing the online MSDN documentation there still seem to be large gaps/flaws/errors in what is documented, and how the API works.

Is there any book about the SharePoint 2007 API that delves deeply into everything? I would think that Microsoft would commission/ship such a book? :)

*I've found "SharePoint 2007 Development Recipes - A Problem Solution Approach" by APress to be very helpful, but I think it barely scratches the surface of the API.

Answer 1

Look into the Inside Microsoft Windows SharePoint Services 3.0

I've had a lot of luck with this book, can't guarantee it goes into EVERYTHING, but it has mostly developer resources...

Answer 2

I agree with Mike above. Also, Inside Microsoft Office SharePoint Server 2007 is a good reference.
