I finished Ann Rockley’s Managing Enterprise Content on the way to the IBM CM & Portal conference last week. The book is a pretty high-level overview of content management, in general. I’d say it would be of most use to those new to the area, people putting together content management proposals, companies writing RFP’s, or managers (business or IT) with responsibility for content management projects or organizations. There’s enough detail to put together a general project approach or help look for potential areas to capture ROI, but not enough for project managers to develop a project plan or for developers or architects to design a solution.
The subject area is content management, in general, which includes web content management. Even with the caveats I’ve given, I’d still say it is recommended/required reading for people working in the space.
