This project was initially funded by the Irish Higher Education Authority's Programme for Research in Third-level Institutions, Cycles 2, 3 and 4 from 2000-2005, and from 2007-2010. Since then, the database has been funded mostly from private funds, kindly provided by Professor J.A. West and Dr P.W. Gabrielson, and by sponsorship. The Ryan Institute and the National University of Ireland, Galway and Galway University Foundation have also contributed extensively with funding, facilities and communications.
