Activate the encyclopedia

To activate the encyclopedia it is necessary to set the user rights for each user group. You can do that on the options page in the "User rights" box: Go to Settings -> Encyclopedia. Scroll down to "User rights" and click on the box title to open the box. Tick "Yes" for all the rights you want to give to a certain user group.

Create and edit terms

After you have activated the encyclopedia feature you can find a new menu entry in your dashboard: "Encyclopedia (or something like this, depends on your settings). Now you can click on "Add Term" to start fill your new knowledge base with contents. The interface is willfully adapted from the original WordPress post and page interface. This way it will be very easy for you to step in.

Screenshot: Edit Term


Taxonomies for encyclopedia terms have the same behavior like the post tags and categories you already know from usual posts. For the encyclopedia you can use categories to classify your terms. Tags are necessary if you want to display related terms anywhere.

To activate taxonomies you need to go to the options page and scroll down to the "Taxonomies" box. There you can activate and deactivate the categories and tags for the encyclopedia post type. Do not forget to scroll to the button and hit the "Save changes" button.

The management of the taxonomies is as easy as the management of the post categories.

Screenshot: Categories

Terms in your encyclopedia can be "related" if they have common tags. Two terms are more related if they have more common tags.

On the options page you can setup that related terms should appear automatically above or below a terms content. If you deactivate this option you can display the related terms manually through adding the [encyclopedia_related_terms] shortcode to the terms content. (With the "number" attribute you can set a limit of how many related terms should be shown.)


Encyclopedia Pro uses the WordPress embedded user rights system to control the access to terms, taxonomies and options. You can change these settings directly on the options page without any external plugin. By default nobody has any right, expect the administrator of your installation - the administrator can see and change the options page. So the first step after activating the plugin should be the capability configuration. Go to your Dashboard -> Settings -> Encyclopedia. Scroll down to the "User rights" options box and open it up with a click on the box title. Then you can set the available capabilities for all existing user groups.

Nothing is more awesome than a plugin which plays well with all the cool WordPress features. You can add all encyclopedia terms and taxonomies to your custom menus. Go to your Dashboard -> Appearance -> Menus.

Encyclopedia archives

The encyclopedia archives are the index pages which lists all your terms. Every encyclopedia index page will automatically be sorted alphabetically and gets a great letter navigation at the top. The letter navigation will be visible only if there are two or more choices for the user. Encyclopedia Pro generates one index page for every category and for every tag. You can find the URLs to these archives in the edit category/edit tag screen in your dashboard.

Template files

All plugin outputs can be changed via user defined HTML templates. Just create the templates you want to overwrite inside your theme folder (no matter if parent theme or child theme). You can find the default templates in the plugin folder in "templates/". Attention: Do not change any plugin files at any time. You will lose you modifications after an update!

This plugin does exactly what I'm looking for and is well worth the PRO version.

David Larson
Nice and well made plugin

A good and well coded encyclopedia plugin. As far as i have tested it, it is the best outta there.

Nicolas Staszak
Awesome plugin

As a language teacher and translator I was looking for a dictionary plugin for my students. The free version is limited, but gives a good insight in the possibilities of the pro version.

And I needed a Dutch version - after translating the plugin into Dutch and sending it to Dennis Hoppe - I decided to buy the pro version. And it works great!

Almost all the software I have has to be annually upgraded, so I was not astonished by the annual upgrading - Dennis Hoppe really helps out and is constantly working on this plugin.

Great for small dict

Just install on my blog, don't know how to use at the begining but after following the instruction on Author home page, everything become easy.

Billy Duc
Good plugin

I am using this plugin on three websites now and have found no problems with the plugin. As with all new plugins it a question of working around compatibility with others and getting to know the plugin. In the end there are no problems I have encountered with this one. It could be developed to add more features but overall very good and does what it says.

Great publishing tool!

All you needs to build a big indexation's project! Highly recomended!

Daniel Boutet

I use this plugin with pre version and i found it wonderful pulgin it make all of my needs… Thanks for Developer :)

Momen Noor
Just what you are looking for!

This is the ONLY plugin for word press that does what wikis do best- Cross linking- not even the bigger, shinier member driven WP communities had the capability of creating a legitimate wiki that actually is self referential. Well worth the money!

Paul Copello
Very Convenient

This is a great plugin because it is highly versatile and can be used as a simple glossary or a fairly complex wiki. I particularly love how it automatically links every reference to my encyclopedia terms back to its source, regardless of where is it posted in my site. It also shows a brief tool-tip when hovering over such links, making this plugin all the more convenient. Definitely recommended if you need an on-site encyclopedia.

Corey Barnes
Excellent Plugin and lightning fast support

Excellent Plugin, simple to use and and lightning fast support from Dennis Hoppe. Thank you very much!

Exactly what we were looking for

Everything in this plugin works as promised. Encyclopedic terms are automatically, and correctly, linked to throughout the site. Simple set-up, great look, and extremely customizable through CSS.

Isabel Ruiz
Simply Great

Simply Great. Small & Fast. Really Great Work!

Erika v. d. B.
Good plugin

Good plugin. Easy to learn. Makes nice search engine friendly urls.

Vincent Raja
Excellent use of custom post types

I only started using this great plugin in February 2013 and I must say I am impressed. I like the use of custom post types - it makes perfect sense. This plugin works brilliantly. Thank you.

Douglas Garza

Fantastic plugin and builds a superb looking glossary.

Sasha Ruzin
Great plugin with awesome support

The greatest value of this plugin is (except for it's powerful features) that it's supported and developed almost on a daily basis.

Gertrude Jordan

It's so sad that the free version don't have plural management but the plugin is really awesome :D

Fran Pérez
Super handy

We were able to use the plugin to construct a glossary from spreadsheet data we have. great plugin with rapid support response time!

Must have

Must have! It is really good.

JuanPablo Barrientos

While there's a few features I'd like to see, this is one heck of a good plugin. We cranked out 281 new and very useful pages in our site in a matter of a couple of hours start to finish. Two thumbs up and six stars.

cassandra hudson
Excellent glossary, excellent support

This plugin, even the free version, adds a real "wow" factor to any website with a lot of specialized vocabulary. It's amazing and refreshingly simple to just hover to get the definition. Support from the developer has been excellent.

Jonathan Moreira
Great support and plugin

Plugin is working as stated, a good choice if you need a glossary. Very good support.

wyatt hunt
Great Plugin and awesome Support

I rarely write reviews, but this plugin really deserves it. It is among the best if not the best Glossary Plugin around. It has a tremendous amount of features and options. And the support is great. I had a few bugs in the first version I downloaded and they were all taken care of in a matter of hours. Keep up the great work!
