Some of the Marx Library's ebook collections require the use of Adobe Digital Editions. This is a free download available for Windows and Mac at http://www.adobe.com/products/digitaleditions/.
However, the Kindle and the Kindle Fire are not supported devices, so EBSCO ebook Collection and ebrary titles are not downloadable to the Kindle nor are they readable through the Kindle Fire's web browser.
For a complete list of devices supported by Adobe Digital Editions, see http://blogs.adobe.com/digitalpublishing/supported-devices.
