Karen,
National Archives of Canada is slowly getting rid of their handing file
cabinets for several reasons.  1). Some are top heavy and when fully
loaded, they tend to tip over when trying to remove maps near the back as
most of the maps are loaded onto the front opening.  We have had to bolt
them together for secturity.  There is the possibility of someone being
skewered by one of the prongs if the cabinet should fall.
2).  For series maps, oversize maps may not fit the cabinet and may have
to be cut, or filed elsewhere which makes it difficult for staff and patrons.
3).  Cost in materials and staff time in attaching the hanging file strip
to all of the maps.
4). Damage to the maps when they are retrieved.  They may get torn, fall
down to the base (its great getting them out), plus the wear and tear on
the maps as they rub against the prongs when they are pulled out.
 
Granted our cabinets are old, but some of the problems will remain even
with newer ones.
