Here's where people who've read CrcCard books and used them in design recommend to the neophyte which books shine:
TheCrcCardBook by David Bellin, Susan Suchman Simone
DesigningObjectOrientedSoftware by RebeccaWirfsBrock, BrianWilkerson and LaurenWiener. This book introduced the concept of ResponsibilityDrivenDesign that CRC Cards are based on. It's amazing to me that an OO book written a decade ago can still be this vital and useful. -- JohnBrewer
