    Abstract
    A study of the online catalogues of major academic libraries and databases in the Netherlands shows considerable variation in the form of name used for the author W.F. Hermans. The problem lies with a lack of authority control in headings used in the Dutch national union Pica catalogue. Reactions from 2 cataloguers point to the difficulties in maintaining catalogues in the face of reduced funding and to the important role played by the Pica project in improving library services and reducing cataloguing backlogs
