Address for database vendor?

[pathology at mscf.med.upenn.edu]

What is the address and telephone number for the Canada Institute for 
Scientific and Technical Information?  The July, 1992, issue of Physics Today 
(page 50) describes this institute as a "unified search service for all major 
crystallographic databases."  Does anyone have any comments about the 
usefulness of this database provider?  Thanks for the information.
