Re: [ccp4bb] Beginning crystallography text

Hi, I found "Crystal, X-rays and Proteins" by Dennis Sherwood very helpful in understanding the basic concepts of crystallography. However, it seems that the book is out of print. It would be great, If anyone here is having an E-copy of this book and can share with us. Thanks, Vineet
