Of the making of Christian books against evolution there may be no end, but adaptation and natural selection are everyday realities in the world of Christian booksellers.  As this article notes, one of the themes emerging from the annual convention of the Christian Booksellers Association is the need to adapt to Walmart and big box stores, who are taking away a sizable portion of the Christian book trade.

What is keeping the booksellers in the black?  Yes, they are beginning to emphasize their more informed selection & ties to local churches, but statistics tell the real tale:  "Books now account for only 40 percent of sales in Christian retail stores." 

Jewelry, tchotchkes, gifts--that's where the profit center now lies in the Christian market.  But if mainstream merchants continue to expand their range of Christian and other religious products, look for more traditional Christian bookstores to go the way of all flesh.
