Buy Architectural Graphic Standards for the details?

[brookefox]

Are either of these worth buying for the details? My needs now are limited and strictly residential.

Architectural Graphic Standards 4.0 CD-ROM, based on the current 11th edition - $375
Architectural Graphic Standards for Residential Construction 1.0 CD-ROM - $325

From the network version description:

What's new in Version 4.0:
* An improved user interface that allows the user to navigate the CD using familiar and easy-to-use web-browser functions
* 100% of the details in CAD-compatible format--15% more than Version 3.0--available in .dwg, .dgn, and .dxf file formats
* Easier search methods--Topic Search, Index Search, Key Word Search, and CSI Code Search

I have a 30% discount available through March 31, received by mail, so I'm guessing anyone could have it.
(I'm not a layout user but understand that is where their use has more purported relevance. For me that is another discussion.)
