An excellent extension of the available Microsoft help docs for anyone using VBA for Office automation. Largely a reference index, but there are a few chapters of conceptual explanation. Strictly covers the VBA language, not the VB6 IDE or any particular Office program's automation library. This much-needed specialization of scope is what makes this book so valuable for anyone using VBA; many peer books focus strictly on Excel or Word, or VB6 development at large.
