How to Save an HTML page as an e-book
Sometimes the e-book you want is only available to read online as an HTML page. Here's how to get it to your e-reader as an e-book.

Select the book in Calibre and Click the Convert button:

Now you can go back to the Convert menu and add a  description, tags, and a cuter cover if you like.  Just search Google images for "book  cover" and the title of the book.
