The book is Crystal Reports Encyclopedia Professional XI Reports Volume 1 by Brian Bischof.  In my review, I found a few areas where I think it doesn't live up to the Encyclopedia designation.  But there are many other areas where it does live up to that.  Another caveat is that this volume is for report designers, not for programming Crystal Reports.  You can see Crystal Reports Encyclopedia Professional XI Reports Volume 2 by Brian Bischof for that information. 

I would recommend this book as a must have for Crystal Reports report designers.  It is a great reference to supplement the materials that come standard with Crystal Reports.
