The document discusses the changing roles of librarians and the possibility of horizontal career development through task rotation and job exchange. It argues that horizontal career development can help librarians stay in control of changes in the profession by developing new skills. A survey found that library administrators were interested in staff exchange but doubted the practical implementation. Benefits included diversified skills, flexibility, growth and understanding between staff. The conclusion is that task rotation and exchange are compatible with the library's values and could include internal rotation or short international exchanges.
