Best Crc Card Book

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

ISBN:0201895358

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
