The ML-N omits subsistence items. The source for
subsistence is the book edition of the Federal Catalog
for Subsistence compiled by the Defense Personnel
It also omits cryptographic/
cryptologic and Defense Nuclear items which are listed
in security classified catalogs produced by the
respective DOD agencies.
The ML-N is a Navy-tailored publication;
therefore, many NSNs may be found in the MCRL that
are not in the ML-N. If the item being researched is not
found in the ML-N (including deleted items) and a
continuing requirement exists, the using activity must
take the necessary action to establish Navy interest. The
format of the ML-N is illustrated in figure 4-5.
For definitions and explanations of the various
codes and information found in the columns of the
ML-N, refer to the Introduction to Federal Supply

The Fleet Material Support Office publishes related
publications that supplement the ML-N by providing

The MCRL published on microfiche provides
cross-reference information from reference numbers to
NSNs (Part 1) and from NSN to reference number (Part
II), to assist in identifying items in the supply system.
(Refer to figure 4-6.)
The MCRL is a consolidated publication and
includes items of supply which are used by all services;
therefore, many NSNs will be listed in the MCRL which
are not listed in the ML-N.
Part I of the MCRL is printed in reference number
Reference numbers are sequenced
You should remember that when looking up a
reference number, several methods of representing the
number may be used. Different arrangements of the
reference number should be tried before deciding that
an item it is no longer listed. For example:
