is specific to the
catalog since it shows what items
are owned by the various member libraries.
catalog and most databases support other types
of limits. Limiting allows you to exclude
information based on criteria.
common limits are:
by date range
(e.g. nothing older than 1993)
(e.g. only things written in Spanish)
(e.g. videorecordings only)
subject specific databases offer limits
that are specific to the subjects
being covered. For instance, ERIC, an
education database, allows you to limit by grade
level (e.g. middle school).
