This paper presents the findings of a study of fill rate, time, and de
livery costs for international document delivery from the Iowa State U
niversity Library to libraries and scholars in several developing coun
tries. The overall results included a 73 per cent fill rate and a tota
l turnaround time of 16.3 days. Per page fax charges were almost 12 ti
mes as expensive-as air mail costs. International document delivery pr
ogrammes will need to have the ability to handle a variety of communic
ation methods. In addition, these libraries will need to examine sever
al philosophical issues arising from interlibrary co-operation with pa
rtners in developing countries as they determine their place in the co
mplex economic, political and organisational structures related to int
ernational document supply.
