Document supply in Canada presents many challenges because of the rela
tively small population spread over vast distances but with the majori
ty concentrated along the United States border. There are large distan
ces between many population centres making the timely delivery of libr
ary materials to users in these areas problematic. In an attempt to ad
dress these issues the National Library of Canada has undertaken a num
ber of studies and initiatives. Describes some of these studies and pr
ovides a brief description of potential solutions.
