Encyclopedia. Another noticeable influence came from futures studies, with which Judge has long been associated. He reports in Encyclopedia Illusions how the narrow focus of the Club of Rome on a few socio-economic aspects of futures research prompted the much vaster exploration concerning world problems and human potential. Anthony Judge was the architect and managing editor of the Encyclopedia. He was also the main author of the notes and commentaries. The principal editors over the years have been, for different editions, Jon Jenkins and Maureen Jenkins (who had also worked at the Institute of Cultural Affairs), Owen Victor, Jacqueline Nebel, Nadia McLaren, and Tomáš Fülöpp. There were also enthusiastic editorial contributions from volunteers. All people related to the UIA who worked directly on one or more of the five Encyclopedia editions figure on a list that can be found online under the heading Associates of the Union of Intelligible Associations. This is because in 2005, following disagreement over the partnership contract, Anthony Judge, as Executive Secretary of Mankind 2000, reframed the Encyclopedia as having been a strategic initiative of the Union of Intelligible Associations. Tomáš Fülöpp continued maintaining and improving Encyclopedia databases at the UIA until January 2012. In the years after, on a contractual basis, he has been architecting a number of data structure, editing system, API, and visualization enhancements. Tomáš Fülöpp also continues to manage and lead the Encyclopedia project in close collaboration with the UIA and a group of senior editors such as Nadia McLaren and Kimberly Trathen.

It is still a single volume (published, this time only, as volume 4 of the Yearbook of International Organizations), but it has a different set of sections, and because it is printed on thin paper with a special world award-winning typesetting, the book is equivalent to several normal volumes. The 3rd edition, initiated in 1988 and published in 1991, has two volumes: World Problems (vol. 1), and Human Potential (vol. 2). The 4th edition, initiated in 1992 and published in 1994–1995, has three volumes: World Problems (vol. 1), Human Potential – Transformation and
