SOME NETWORK INFORMATION CENTER POLICIES ON HANDLING DOCUMENTS
INTRODUCTION
The Network Information Center (NIC) seeks to facilitate the flow of
information between sites on the Network and to and from other
stations whose work makes them valuable as participants in the
Network dialog. The NIC is concerned both with the techniques for
the flow and with optimizing the content of the information itself.
Some aspects of the work of the NIC in support of information flow
are described here, and some suggestions made to Network participants
of ways they can help this work.
All information handled by the NIC is available to any Network
participant. All information generated by the NIC is unclassified
and is without distribution limitation except as dictated by staff
and budget size. Any information sent by an originating party to the
NIC for recording or distribution is presumed to be unclassified and
without distribution limitations as well. Any statement carried by a
document thus submitted which seems to imply a limitation on
distribution, quotation, or citation is presumed not to apply to its
handling by the Network Information Center.
NIC NUMBER
One important function of the Network Information Center is to make
records of the existence of RFC's, formal NIC-related manuals and
reports, Network memos, other Network informational items, and other
informational items of interest to Network participants, and to index
these records so that such items can be recalled when needed.
To tag the informational items a serial number is assigned by NIC.
The serial number has no intrinsic meaning, not even necessarily an
indication of sequence of issue. It is a unique identifier and can
be used to refer to the item in further communications, to facilitate
indexing, and to allow numeric filing of documents.

Use of the NIC number has advantages in online dialog which are not
yet demonstrable around the Network, but the cooperation of Network
participants in applying one when a document is originated is
important.
THE NIC CATALOG
Items of information relevant to the Network appear in many forms,
including technical reports, RFC's, brief network memos, journal
articles, and letters. Reference to these is simplified by
assignment of a NIC number to each. To record the item to which the
NIC number refers, a description of each item, using a set of
standard data elements, i.e, author, title, etc., is coded and
entered as an online system (NLS) statement into a machine file.
An example of a statement with typical coded data elements:
(A5480) *a1 James E. White #2 org *b2 University of California
at Santa Barbara #3 Computer Research Laboratory #5 Santa
Barbara, California *c1 An NCP for the ARPA Network #6 142p.
*d1 21 December 1970 *f1 r *f2 o *rl UCSB CRL 12 *31 ARPA #6 AF
19628-70-0-0314 *w2 3-11-71 *y1 Describes program designed and
implemented at Santa Barbara node of ARPA Network, written in
assembly language and implemented on 360/75. Discusses
interface with hardware, software, and operator. *y3 Host-
Interface protocol; Host-IMP protocol; User-NCP protocol;
Host-Host protocol; Host-IMP messages, IMP-Host messages *z1
all *z2 NIC *z3 new *
The group of files at ARC containing these statements of data about
NIC items and other informational items is the Master Catalog. The
term NIC Catalog refers to the machine file created by collecting the
statements coded *z2 NIC in the Master Catalog.
The data element *z1 indicates which Stations hold a copy of an item;
not all items related to NIC are sent to Stations, and in the future
it is expected that Stations will submit many documents to NIC for
cataloging which are not held by other Stations.

NIC CATALOG LISTINGS AND INDEXES
Programs have been written at ARC to collect, sort, analyze and
format the statements and the data elements in the statements to
produce catalogs and indexes such as those in the Current Catalog of
the NIC Collection, NIC (5145,).
The Current Catalog of the NIC Collection is a functional document,
as explained in Branch 3 below. It has as its contents, at any time,
the current issue of a bibliography of items from the NIC Catalog,
called a NIC Catalog Listing, and author and keyword indexes.
Examples of entries in the Catalog Listing and in indexes are shown,
using the statement above:
Catalog Listing by Author:
An NCP for the ARPA Network
James E. White (University of 5480 White
California at Santa Barbara)
21 December 1970
Describes program designed and
implemented at node of ARPA Network,
written in assembly language and
implemented on 360/75.
Discusses interface with hardware,
software, and operator.
Catalog Listing by NIC number:
An NCP for the ARPA Network 5480
James E. White (University of
California at Santa Barbara)
21 December 1970
Describes program designed and implemented
at node of ARPA Network, written in
assembly language and implemented on
360/75. Discusses interface with
hardware, software, and operator.

A NIC Catalog Listing will indicate those items held in the Station
Collections either by a separate listing or by a notation with each
reference. A number catalog or index serves as a shelf list of
documents held by a Station. The indexes are not limited to the
Station Collections but lead to the entire Catalog.
DATA ELEMENTS
The data elements for information items include the author, title,
addressee, date, other numbers, keywords, and abstract. When these
elements do not exist in the item, they are supplied by a NIC
cataloger if possible. In online communication around the Network,
"online dialog", several of these elements of data will be recorded
automatically. Lacking online recording, it is important that
originators of reports, memos, and other such items be diligent in
including these data in their transmissions.
For memos, essential data elements which the originator
should supply are:.
author(s)
address(es) of author(s)
addressee(s)
address(es) of addressee(s)
date of origination
subject of memo
A preassigned NIC number is desirable. A number for
assignment can presently be obtained by calling NIC, and
soon will be obtainable online.
The addressees of a memo can of course be a group, such
as the Network Working Group, or the Glitch Cleaning
Committee, in which case the NIC needs a list or
reference to a list of the people in the group.
