This is a plugin that simplifies the integration of the Jellybooks DISCOVERY service API, and embeds interactive book samples within product pages on a WordPress site:
<ol>
<li>It connects to the Jellybooks DISCOVERY API to retrieve book samples for a given ISBN.</li>
<li>It automatically adds interactive book samples to your book product pages via our excerpts.js library.</li>
</ol>
Note: For the avoidance of doubt, admins must have a valid Jellybooks DISCOVERY account and API key to use this plugin.
For further information about the API: https://www.jellybooks.com/apis/excerpts/index.html 
For further information about the excerpts.js library: https://www.jellybooks.com/apis/excerpt_integration/index.html. That page also explains some of the various options that are configurable in the plugin admin interface.
<h3>Source code</h3>
The plugin can be downloaded and its source code can be viewed and modified (as per Open Source license). The plugin also contains Jellybooks’ <a href="https://github.com/Jellybooks/excerpts-js" rel="nofollow ugc">excerpts.js library</a> in a minified form for improved performance.
A non-minified version is included within the assets directory. The full source code for the excerpts.js JavaScript and CSS files can be found in the <a href="https://github.com/Jellybooks/excerpts-js" rel="nofollow ugc"><code>excerpts.js</code> repository</a>.

WordPress Goodreads Bookshelf (aka Bookshelf) allows you to display a custom list of books from your <a href="http://goodreads.com" rel="nofollow ugc">Goodreads</a> shelves anywhere on your site that PHP is allowed.
<ul>
<li>You can choose from any one of your bookshelves including your custom shelves on <a href="http://goodreads.com" rel="nofollow ugc">Goodreads</a>.</li>
<li>You can specify how many books it should retrieve from the shelf and how often it should update the list on your site.</li>
<li>You have full control of how the list is displayed using your own HTML and CSS. So you can easily make it blend in with the rest of your blog.</li>
<li>If you have a private account on <a href="http://goodreads.com" rel="nofollow ugc">Goodreads</a> there are specific instructions to set up Bookshelf so that it retrieves your books, but your profile can still remain private.</li>
<li>You can use all the standard information (title, author, cover image, isbn) as well as some more detailed information such as rating, date read, review, and many more.</li>
</ul>
Lots more features to come…
