As I do not have full integration into Stanza you will need to manually add the epubBooks.com website as a Book Source. Here are some step by step instructions:
* Open Stanza
* Click the Get Books icon at the bottom of the screen.
* Select the Shared tab at the top of the screen.
* Click the Plus (+) button (top-right).
* Enter a name (epubBooks) and this URL: www.epubbooks.com
* Select the Web Page button.
* Click Save
