Today the Leica D-Lux 5 book is still not listed as available from Amazon.com, but it did show up for the first time on the site of Barnes & Noble, BN.com. The listing says the book ships within 24 hours, which should be correct, because the book is available to online sellers through Lightning Source, the print-on-demand company that prints the book. Here is a link to the listing for the D-Lux 5 book at BN.com.
As of now, the morning of December 23, Eastern time in the U.S., I still have a few books available for sale directly from this web site, at the Leica D-Lux 5 page.
