Where To Find SIRS Subscription Numbers
All library subscription numbers for the Service Information Retrieval System can be found in one place--the Miscellaneous Section of the Publications List. See Illustration 1.
Illustration 1. Library subscription numbers are in the Media Number Column.
Illustration 2. At this time the grid location is N1.No two dealers need microfiche libraries in exactly the same quantities nor in complete sets. Each library is available separately.
When you order SIRS libraries, use the Publications List Insert to find the correct fiche and grid location of the subscription numbers.
Illustration 2 shows part of the Insert with the reference to "Microfilm...N1 (includes library subscriptions)".
