Since the barcode has evolved to serve as a circulating device rather than an inventory device, barcode each separate item that can circulate. Whether or not the accompanying material will circulate separately, or at all, is a local library decision and does not affect the practice of barcoding the material.
Do not barcode:
-- maps, photographs, slides, charts, or fiche contained in a pocket physically
attached to the main text
-- loose and/or folded sheets of paper
-- booklets in the jewel cases for audio compact discs or CD-ROM discs
-- booklets in the cases of DVDs
Barcode:
-- all other types of accompanying material
If accompanying maps, photographs, slides, charts are in a separate container (such as a folder): barcode the container and not the contents.
If a score and parts on are on the same bib record, barcode the score only (see "Music: Scores with parts" below).
If a score and parts are on separate bib records, barcode the score, and barcode the parts with one barcode (see "Music: Scores with parts" below).
Examples:
-- text accompanied by computer disk: 2 barcodes (text, disk)
-- text accompanied by booklet: 2 barcodes (text, booklet)
-- text accompanied by 2 reels of microfilm: 3 barcodes (text, each
reel)
-- text accompanied by map in pocket glued to back cover: 1 barcode
(text)
Generally, write the call number either on the accompanying material (or its container), or on a label to be affixed to the accompanying material (or its container), whatever is appropriate.
Do not add a call number to:
-- pockets physically attached to main text containing maps, photographs, slides,
or charts
-- loose and/or folded sheets of paper
Add a call number to:
-- all other types of accompanying material, including maps, photographs, slides
or charts contained in pockets physically attached to main text
-- booklets in the jewel cases for accompanying audio compact discs or CD-ROM
discs
-- booklets in cases for accompanying DVDs
-- each score and part
If maps, photographs, slides, or charts are contained in a separate container not physically attached to the main text, add a call number to the container.
The call number for the accompanying material consists of:
-- the call number of the item it accompanies, and
-- a term describing the accompanying material (see "Terms" below).
Examples:
TA175.6
.G68
1987
guide
PA145
.S78
2004
DVD
Terms for accompanying material
Note that the term for the accompanying material appears at the end of the call number on both the piece itself and on the online item record. It may help to think of the term as a kind of volume designation.
Do not confuse this term with the call number prefix that may appear online; the call number prefix is used to decribe material type and to determine circulation policy--it is not a part of the call number proper and should not be written on the accompanying material.
Important things to remember about accompanying material
terms:
-- used in call number on the item and 949 $v
-- each term should be consistent with term used in bib record (300
$e or 500)
but
-- terms do not have to match exactly:
-- use shortest form possible without abbreviating or omitting
differentiating information
Examples of appropriate terms: atlas fiche book guide booklet manual cassette notes disk pamphlet tape CDROM
If bib record term is "lengthy" (more than 8 characters), shorten to most essential element. For example:
| MATERIAL |
SHORTEN TO: |
| microfiche |
fiche |
| sound cassette |
cassette |
| student guide |
guide |
| computer disk |
disk |
| 1 set of user's notes |
notes |
| teacher's manual |
manual |
| sound disc (compact) |
CD |
| computer laser optical disc |
CDROM |
| DVD (computer versatile disc) | DVD |
However, do not shorten the term if it creates ambiguity. For example, if a book is accompanied by a teacher's manual and a student's manual, do not shorten both of them to "manual." Retain the differentiating part of the terms; use both "teacher's manual" and "student manual."
If the accompanying material is referred to as "1 v." in the bib record, use a term that best describes what the material is. Example: "book" or "booklet." If the accompanying volume is more specifically labelled, use that term. Example: "guide" or "manual".
If an item is accompanied by two different items in the same format, differentiate them either with terms or numbering from the pieces themselves, or arbitrarily with whatever makes the most sense. Example: a book accompanied by two computer disks, neither one numbered: use "disk 1" and "disk 2."
If it is clear that two or more accompanying computer disks have the same contents but use different platforms (e.g. IBM, MAC, Windows), label them so that the distinction is clear, assigning numbers to the disks only when necessary:
IBM disk, MAC disk, Windows disk.
IBM disk 1, IBM disk 2, MAC disk 1, MAC disk 2
On one bib record. If a score and parts are cataloged on the same bibliographic record, assign a single barcode to the score. Do not separately barcode or create separate holdings for the individual parts. Write the call number on each of the parts.
On separate bib records. If a score and parts are cataloged on different bibliographic records, assign one barcode to the bib record for the score and one barcode to the bib record for the parts .
Record the term denoting the accompanying material in field 949 $v. (See Terms above.) If the location and material type for the accompanying material is different from that of the main text, and if it is supplied on the order slip, then add it to the 949. Otherwise, the default will be applied.
Note: questions often arise, especially from processing staff, as to why accompanying material in special formats will have their material type appear twice in the call number in the online catalog. The reason for this is, of course, that the material type appears both in the delimiter k subfield of the 852 of the holding and in the volume designation, as befitting an addition to the main item. An accompanying book item that merely gets "Suppl." added to its volume designation won't raise any eyebrows because it will appear only once, under the call number.
An example of a text accompanied by a user's manual:
300 156 p. ; $c 26 cm. + $e 1 user's manual (18 p. ; 18 cm.)
949 e $p 39080004227245
949 e $p 39080004227246 $v manual

Examples of Aleph displays of computer disks and CDROMS:
Some libraries keep computer disks at the circulation desk (CIRCD), others on reserve (RESDK). The user's guide is sometimes kept at the circ desk with the disk, but catalogers are not responsible for recording this information unless it is clear from cataloging instructions in the on order record. If such is the case, see third example below. Barker and Science now shelve accompanying CDROMs with the book in the stacks (STACK); Dewey retains them at reserve (RESDK).
These examples are by no means exhaustive; for further details see Expansion Code List.
