Not Swallows & Amazons, not yet, but several editions of Old Peter's
Russian Tales and the Russia journals have been published in Kindle
format and can be easily found by going to the Kindle store on the
Amazon site and searching on "Arthur Ransome."
The Kindle is a wonderful reading device, with a stand very good for
reading in bed or at table and very easy on the eyes. Books that
aren't in Kindle format now have a place to click on "I'd like to read
this book on Kindle," so I'm hoping for many additions to my list.
