CHARACTER POSITION DEFINITION AND SCOPE
Computer files definition of field 008/18-34 is used when Leader/06
(Type of record) contains code m. Field 008 positions 01-17 and 35-39 are defined the
same in all 008 fields and are described in the 008-All materials section.
Field 008/18-34 correspond to equivalent positionally defined data elements in field
006/01-17 when field 006/00 (Form of material) contains code m (Computer file/Electronic
resource). Details about specific codes defined for the equivalent character positions
in field 006 and 008 for computer files are provided in the
Guidelines for Applying Content Designators section of 008-Computer
files only.
GUIDELINES FOR APPLYING CONTENT DESIGNATORS
■ CHARACTER POSITIONS
18-21 - Undefined (006/01-04) Undefined; each contains a blank (#) or a fill character (|).
22 - Target audience (006/05) One-character alphabetic code describes indicates the target audience for which
the material is intended.
Used primarily for educational electronic materials. When items with factual
content are considered appropriate for more than one target audience, the code is
recorded for the primary target audience.
If the record has both reading grade and interest age information present in the
521 (Target Audience Note) field, 008/22 is coded based on the interest age
information.
# - Unknown or not specified Target audience for which the material is intended is unknown or is not
specified.

and 2) items which address a limited audience, for example, the employees of a
single organization.

(|).
26 - Type of computer file (006/09) One-character alphabetic code that indicates the type of computer file described
in the bibliographic record.
Specific type of electronic resource is also described in textual form in field
516 (Type of Computer File or Data Note).
a - Numeric data Mostly numbers or representation by numbers, such as records containing all
information on student test scores, all information on football team
statistics, etc. Information may be original surveys and/or information that
has been summarized or statistically manipulated.

and identifying the information and mechanisms required. Includes videogames
and microcomputer software and computer models. Some types of computer programs
(e.g., game, font) are identified by separate codes in this character
position.

other types of files to produce graphic patterns that can be used to interpret
and give meaning to the information.

converted into a coded format that can be processed, sorted, and manipulated by
machine, and then retrieved in many optional formats. Includes language
material intended to constitute a textual document, whether represented as
ASCII or image data. Includes both single bibliographic entities or a
collection of bibliographic entities. Documents whose primary purpose is
textual, even if search software is present, are coded here.

citation databases. The data may be in a structured or unstructured form.
Search software may be present, but the purpose of the record is description of
the content of the bibliographic data or database, rather than description of
the online system or service.

##$aAudio data (Digital audio file) |
i - Interactive multimedia Supports navigation through and manipulation of many kinds of media (i.e.,
audio, video, etc.). Interactive multimedia usually gives the user a high level
of control, often allowing almost conversational interaction with the computer
and data.
j - Online system or service May contain nonbibliographic information. An online system or service supports
system-based user interaction. If the focus of the record is to describe the
system itself, with the content of the databases incidental contained therein,
it is coded here. If the resource is an online file where the system is
incidental to the description, it falls into another category. Examples of
online systems or services are: online library systems (consisting of a variety
of databases), FTP sites, electronic bulletin boards, network information
centers.

27 - Undefined (006/10) Undefined; contains a blank (#) or a fill character (|).
28 - Government publication (006/11) One-character alphabetic code that indicates whether the computer file is
published or produced by or for an international, national, provincial, state, or
local government agency (including intergovermental bodies of all types), any
subdivision of such a body and, if so, the jurisdictional level of the agency.
Government bodies and all their subdivisions are treated as government bodies
regardless of how they may be entered as headings (i.e., entered under
jurisdiction or not). In the bibliographic record, the body does not have to be a
main or added entry, but it should be named as publisher, etc. in the publication,
distribution, etc. area, or have caused the item to be published (usually inferred
when the governmental body is responsible for the content of the work). When in
doubt, treat the item as a government publication.
Guidelines for certain types of publications
- Socialist countries- Since the coding of all items published
in socialist countries as government publications would limit the usefulness of
this element, coding should be used only for the same type of bodies that would
be considered government in a non-socialist country. In coding items in this
manner, when in doubt, treat the item as a government publication.
- Two levels- If an item is published or produced jointly by
government agencies at two different levels, record the code for the higher
government level.
- Academic publications- In the U.S., items published by
academic institutions are considered government publications if the
institutions are created or controlled by a government.
- University presses- In the U.S., items published by university
presses are considered government publications if the presses are created or
controlled by a government (e.g., state university presses in the United
States).
# - Not a government publication Not published by or for a government body.

CONTENT DESIGNATOR HISTORY
008/18 - Frequency [OBSOLETE, 1995]Defined codes were: # (No determinable frequency), a (Annual), b (Bimonthly), c
(Semiweekly), d (Daily), e (Biweekly), f (Semiannual), g (Biennial), h (Triennial), i
(Three times a week), j (Three times a month), m (Monthly), n (Not applicable), q
(Quarterly), s (Semimonthly), t (Three times a year), u (Unknown), w (Weekly), and z
(Other). For serially issued computer files, frequency can be coded in field 006/01
configured for serials.
008/19 - Regularity [OBSOLETE, 1995]Defined codes were: # (Not applicable), n (Normalized irregular), r (Regular), x
(Completely irregular), and u (Unknown). For serially issued computer files,
regularity can be coded in field 006/02 configured for serials.
008/22 - Target audience [NEW, 1988] [USMARC only]Prior to the definition of this element, the byte was undefined. Prior to 1993, when
code j (Juvenile) was defined, juvenile materials could only be identified by codes a
(Preschool), b (Primary), and c (Elementary and junior high).
c - Elementary and junior high [RENAMED, 2002]
d - Secondary (senior high) [RENAMED, 2002]
008/27 - Type of machine [OBSOLETE, 1989]Defined codes were: a (Computer readable), z (Other).
