There has always been a difficulty in finding out possible funding sources for scientific work on refinement, reduction or replacement of animal experiments - the 3R alternatives. Barbara Orlans in her book In the Name of Science: Issues in Responsible Animal Experimentation (Oxford University Press, 1993) started a list of possible sources; this list was amplified and presented by Amelia Tarzi at the First World Congress on Alternatives and Animal Use in the Life Sciences, held in 1993 in Baltimore (USA). A new and expanded list under the authorship of Orlans and Tarzi has now been published as a directory by the American Society for the Prevention of Cruelty to Animals. It contains the names, addresses, policies and sometimes indications of monies available of 59 organizations scattered across some 16 countries.
