For many decades, the German organization called Evangelische Zentralstelle für Weltanschauungsfragen (EZW - in English: Evangelical Center for World Surveys) has kept documents and articles about UBF. Just recently, they made some of these public on their website. http://www.ezw-berlin.de/html/suche.php?query=ubf&cat=Publikationen Here is an excerpt: "UBF focused especially in the university area. In doing so, UBF poses often as an ecclesiastical student community with international appeal. Students and young people will be attracted to a non-committal and unconstrained invitation, such as "to a cup of tea, to the Bible study or simply to worship". Soon the newcomer finds that he has an appointed "shepherd", and he is now his shepherd's "sheep", and so-called "1 to 1 Bible study" starts."
