SUBJECT INDEX AND TABLE OF CONTENTS TO
QMS ADVISORY CIRCULAR SYSTEM
Attached is an updated cross-reference subject index and an
updated table of contents to the QMS Advisory Circular (A/C)
System. These documents reflect additions and replacements of
A/C's. This index and table of contents supersedes those
issued July 20, 1979 which are obsolete and should be discarded.
Because A/C's are frequently replaced or updated, we will no
longer revise the subject index and table of contents in their
entirety. Rather, we will issue only the appropriate amended
pages to these documents whenever it is appropriate following
issuances of new A/C's. These index and content amendments
will be issued along with new A/C's or by letter from the
Director of the Certification Division in Ann Arbor, Michigan.
