CodeIgniter-Amazon is a CodeIgniter library which assists in the development of applications using the Amazon API.

It's focused on retrieving books with a keyword search, but can be modified to search other areas as well.

Note, this is a very simple implementation and requires some more love, but SHOULD work out of the box.

$this->load->library('Amazon_API');
$this->amazon_api->getBooks("guide, travel, rome");

Add error-handling and clean up code.
