One of the largest research collections at Maynooth University Library ( https://www.maynoothuniversity.ie/library ) is the Hibernian Bible Society (HBS) collection, which contains over 2,000 bibles in more than 600 languages. In 1986 the HBS bible collection was permanently deposited in the Russell Library ( https://www.maynoothuniversity.ie/library/collections/russell-library ) at Maynooth University ( https://www.maynoothuniversity.ie/ ) and St Patrick’s College, Maynooth (http://maynoothcollege.ie/). A series of sheaf catalogues accompanied the collection, providing important details relating to provenance and imprints. Items in the collection have retained their original shelf-marks and are identifiable by the prefix ‘HBS’. Highlights of the collection include copies of the first published edition of the Greek New Testament, the King James Bible and the earliest edition of the Old Testament in Irish.1 A decision was made in late 2016 to catalogue material in the HBS collection retrospectively, as part of the Russell Library Cataloguing Project.
