How can I find the Kindle edition of a printed book?
You can use the AlternateVersions response group
to find the Kindle edition of a book.
For example, consider the book The Complete Idiot's Guide to Publishing Children's Books. The ASIN/ISBN of the printed hard-bound version of the book is 1592577504. To find the Kindle edition of the same book, do an
ItemLookup on the ASIN (1592577504) with ResponseGroup=AlternateVersions:
>>> View ItemLookup for 1592577504
In the AlternateVersions element, you find the ASIN of the Kindle edition - B0017SYMX0.
