Following intensive preparatory work, the UBS Greek New Testament, the most widely used edition of the Greek New Testament worldwide, is now available in a revised and improved edition the UBS 5th Revised Edition (UBS 5). Changes include 1) The readings of the newly discovered Papyri 117 127 have been incorporated into this edition, thereby opening up interesting perspectives particularly for Acts of the Apostles. Besides, it is now displayed in the apparatus, where selected modern Bible translations (English, German, French, Spanish) are based on a variant reading rather than the principal version of the text. 2) A special focus of the revision was on the Catholic Epistles, in which the edition has been made consistent with the Second Edition of the Editio Critica Maior and the 28th Edition of the Nestle-Aland Novum Testamentum Graece. This has led to more than 30 modifications in the reading text and resulted in a new selection of witnesses for the textual apparatus, in addition to modifications of the selection of apparatus units. 3) The Discourse Segmentation Apparatus has also undergone thorough revision. 4) Finally, the UBS 5 edition was typeset with a new, aesthetically appealing and readily legible Greek font.--Publisher
