WordPress gives us a lot of ways of classification: categories, tags, date … All of these methods are efficient, and cover most of our needs. But they are applied to all posts, and don’t allow differenciating or highlighting some specific posts. 
Sometime, it may be helpful to group items into folders or into series, in order to promote these posts, or simply because they belong to a logical sequence, such as tutorials with several stages.
The EG-Series plugin gives a set of easy and ergonomic functions to manage series of posts. This plugin allows to include posts into series, to create, delete or rename series. It also includes widgets and shortcodes to display list of series, or the list of posts belonging to the series of the current post.
EG-Series use only standard tools of WordPress, and doesn’t create additional tables or objects in WordPress. The version 2 of the plugin uses the taxonomies. The main advantages are:
<ul>
<li>The plugin was created in order to reduce as possible, manual operations, and reduce the number of errors,</li>
<li>EG-Series is fully customizable: users can choose the label of shortcodes, and slug used for series’ link,</li>
<li>It can be installed and configured very quickly. It also allows to modify a lot of posts without editing them.</li>
</ul>
With this plugin, you can:
<ul>
<li>Add / Delete a post from a serie,</li>
<li>Create / Rename / Delete series,</li>
<li>Display the list of series in a post, or display this list in sidebar, with widgets for exemple,</li>
<li>Display list of posts, using an another shortcode, or an another widget,</li>
<li>Automatically insert the list of posts of a specific serie, without using shortcode.</li>
</ul>
EG-Series is TinyMCE Integrated. That means you don’t need to learn the shortcode syntax. The plugin adds a button in the tinymce toolbar. You just have to click on this button, choose parameters/options, and click insert. That’s all, the shortcode will be insert into your post with the right parameters.

EG-Series

I've been using this very capable plug-in - almost a suite of plug-ins - for organizing and displaying posts in series for several years. I should have given it a positive review long ago.
The only reason I would hesitate to recommend it to others is that it has not been updated in two years. It also has some very minor functionality and language glitches and less than comprehensive documentation.
In addition, not being updated/supported means that some problems have crept in. After the WP Core upgrade to 4.2, the widgets stopped appearing: It turned out, however, that a fix was very simple (see Support Thread: https://wordpress.org/support/topic/has-the-latest-version-211-lost-its-widget?replies=5#post-8181189). 
So, you should be prepared to do some figuring out for yourself, although, once you do figure it out, you'll find that it works very well, it comes with rich options for alternative display and linking modes, and that the pieces are knit together quite well.



4 Stars not 5 only because no longer supported

Two custom fields (Series and Series Position) need to be added to each post in the series; these fields are used for selecting the posts and ordering them when the index is displayed.
Shortcode [series-index] is placed in the post where you want the index.
Shortcode [series-index-link] can be used in a post to link back to title post.
