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>.

This is a “set it and forget it” widget which allows you to display shelves and reading progress from your Goodreads profile. You can add multiple widgets and configure them individually to show multiple shelves.
Some configuration options:
<ul>
<li>Large/small cover images</li>
<li>Message to display if shelf is empty</li>
<li>Sort books by reading progress, date updated, shelf position, author, title, etc.</li>
<li>Number of books to display</li>
<li>Display your rating</li>
<li>Show first line of your Goodreads review (intended for quick notes such as “reading this together with Alice”, “recommended by Bob”, links to reviews, or whatever else strikes you fancy)</li>
<li>Show reading progress bar, progress text (no bar) or don’t show progress at all</li>
<li>Display time since last update (e.g. “2 days ago”)</li>
<li>Custom strings for time since last update (e.g. for quick and easy translating, or to change “2 days ago” to “2 floobargles since last update”)</li>
</ul>
Almost all HTML elements have dedicated CSS classes to allow you to easily override the style. The widget looks OK on the most popular WordPress themes.
Requires PHP 5.4 or later (PHP 7 supported).
The source is hosted on <a href="https://github.com/cmeeren/gr-progress" rel="nofollow ugc">GitHub</a>.
