We can all look at the redesigned U.S. bank notes in circulation and see the colors and other changes, but some people want more — more information about the why's and the alternatives considered.

Well, take a look at the National Academies' 2007 National Research Council report titled A Path to the Next Generation of U.S. Banknotes: Keeping Them Real. It's got some of that information. The report title link takes you to a page where you can buy a hard copy or PDF of the report, but the report also available there to read free using their online function.

I've mentioned this report previously, but was reminded of it today by a recent post at the Curator & Collector blog, which linked to this National Academies story. Thanks C&C!
