Photocopying

Re Lora Brueck's questions regarding single- and double-page
photocopying: Some volumes open easily for photocopying (particularly
those that are adhesive bound or sewn in signaures, and in which grain
direction runs parallel to the spine of the volume).  Others have to be
manipulated excessively to be photocopied successfully.  If ILL staff
exercise judgment in determining when two facing pages can be copied,
and when it best to copy only one, the interests of preservation can
probably be served at minimal cost.  Paper quality, the condition of
bindings, and the width of inner margins all figure into the decision
making--but reaching the right conclusion probably requires more common
sense than preservation expertise.
