Leader/06 Type of record

Character position definition and scope:

The Type of record character position contains a one-character alphabetic code that is used to differentiate MARC records created for various types of content and material. The code is also used to determine the appropriateness and validity of certain data elements in the record.

Enter more specific information about the material in other fields in the record. For example, a specific type of projected medium, like a slide, would be described by a code in the Fixed-length Data Elements field 008/33 VM: Type of visual material.

Microforms, whether original or reproductions, are not identified by a distinctive Type of record code. The type of material characteristics described by the codes take precedence over the microform characteristics of the item.

Computer files are identified by a distinctive Type of record code only if they belong to certain categories of electronic resources as specified below; in all other cases, the type of content characteristics described by the other codes take precedence over the computer file characteristics of the item.

Determination of the code for a multi-item bibliographic entity (types of material are those specified by values a through t in the table below):

Items are multiple forms of material:

- o (Kit) -- entity is issued as a single unit; no type of material predominates

- p (Mixed materials) -- entity is a made-up collection; no type of material predominates

- other codes -- entity is a made-up collection; one type of material predominates

Items are all one form of material:

any except o or p -- all cases

Record requirements (National-level and Minimal-level) for Leader/06 for all types of material: Mandatory.

Validity by material type: Leader/06 is valid for all types. Each code in Leader/06 is valid for the material type listed in the Field 008/18-34 definition column in the table below:

Code:	Type of record description:	Field 008/18-34 definition:
a	Language material	If Leader/07 = a, c, d, or m: Books If Leader/07 = b, i, or s: Continuing resources
c	Notated music	Music

e	Cartographic material	Maps
f	Manuscript cartographic material	Maps
g	Projected medium	Visual materials
