I wasn't quite sure where to post this, but got disappointingly little response on the BC site, so I've now put it here and under giveaways:

Basically, today is the anniversary of Potok's birth. If you have a Potok on your shelf, please consider releasing it today. I'll give a book to one person who does so. Details are in the other thread. Thanks!!

Thanks, everyone who had a look at this. Since there's nobody to give the book to this year, I'm going to make it a book ring - I've posted here: http://z14.invisionfree.com/Temporary_Book...p?showtopic=715
