….In A Nutshell
Uses Native Interface
to search “foreign”
databases
What’s It Good For?
Search “foreign” databases using familiar
search interface
Search multiple databases simultaneously
if desired
Avoid complex record downloads from
utilities
Workflow flexibility
Communications Protocol
Not limited
to Bib world
or III client
Zee What?
Began with LC OCLC WLN RLIN
Z39.50 is the 50th NISO standard, 1988
NISO was once the Z39 committee of
ANSI
Latest version Z39.50-2003
Maintaining the Standard
Caveats
Doesn’t
standardize
user interface
Doesn’t rank
results for
relevancy
Doesn’t
compensate
for local
practice
Behind the Scenes
• Local user searches in normal way
• Z-client translates search into z-speak
• Z-server receives z-speak --translates
into search request
Remote database receives request-returns records to z-server
