Structural Reference Manuals

[JBrew]

I'm starting to assemble references and study materials for the PE Exam. I'm going to take the PE-Civil with Structural depth this year, and probably the SE I/II in the next year or two. So seeing that I plan to take both the civil and structural PE which reference would be better (or are both unnecessary)?
