The Urantia Book Encyclopedia consists of a series of web pages, one for each specific subject or topic in The Urantia Book, that compile all relevant information that appears in the book on that topic. It is based on earlier work by the Fellowship called Topical Index, but this work is only an index. The creation of the Encyclopedia goes much further by forming a more complete and comprehensible, as well as linked text of all the topics listed in the index.
The topic pages are attempted to be automatically linked when content from The Urantia Book or the Bible is uploaded using the Urantiapedia Tools software, which is responsible for generating these pages. Thus The Urantia Book (and in the future the Bible) have added links in the text that lead to the Encyclopedia, and conversely, one can go from the pages of the Encyclopedia to the paragraphs of The Urantia Book or the Bible that have been mentioned in each topic.
Some examples of topics are concepts like absonity, or people like Grandfanda, or types of beings like Thought Adjusters, or places like Nazareth or Orvonton, or events like the arrival of Adam and Eve, etc.
There is currently a catalogue of more than 4,000 terms created, and a first version of them is being created in Spanish, English and French. Once this first version in these languages is finished, an appropriate technical mechanism will be sought to facilitate the translation into the rest of the languages.
