From the Manage tab, click on Hosted Ebooks from the left column to show a listing of all your hosted ebooks. The management options are straightforward.
Publishing and viewing
The View button will open the hosted ebook in your default internet browser. You can publish your ebook by clicking on the Publish button. Similarly, you can unpublish in the same way. Unpublishing may be useful sometimes for preventing people from accessing your ebook until you make a certain edit or update.
Editing your ebook content
A very desirable option for you is the ability to edit your ebook content on the fly. You do not need to create a new ebook to replace your current one. Click on the Edit button, and choose Download to Edit. The ebook content will be downloaded to your editor, where you can perform your required changes. Once you are ready to submit those changes, click on Apply changes online at the bottom of the page.
In some cases, you may want to use this ebook content in other places, or export it elsewhere. In this case you will need to detach it from its hosted ebook. You can do so by clicking on the Detach button at the bottom of the page.
Deleting your ebook
You can delete a hosted ebook by clicking on the Delete button. This will release that hosted ebook, allowing you to host another instead.
