006 Fixed-Length Data Elements - Additional Material Characteristics (R) (Variable Control Field)
Field definition and scope:
Field 006 contains 18 character positions (00-17) that provide for coding information about special aspects of the item being cataloged that cannot be coded in field 008 (Fixed-Length Data Elements) . It is used in cases when an item has multiple characteristics (e.g., printed material with an accompanying cassette). It is also used to record the coded computer file aspects of electronic items coded in Leader/06 as something other than code m.
The field has a generic tree structure, whereby the code given in 006/00 (Form of material) determines the data elements defined for subsequent character positions. Except for code s (Serial), the codes in field 006/00 correspond to those in Leader/06 (Type of record) . For each occurrence of field 006, the codes defined for character positions /01-17 will be the same as those defined in the corresponding field 008 (Fixed-Length Data Elements). The fixed-length data elements defined for field 006, like the corresponding field 008 data elements, are potentially useful for retrieval and data management purposes.
National-level and Minimal-level record requirements for field 006 for all types of material are Optional.
Field 006 is repeatable .
Guidelines for applying content designation:
Field 006 has no indicators or subfield codes . The data elements are positionally defined by form of material.
Character positions that are not defined contain a blank (#). Character position 00 always contains one of the 15 codes that identifies an additional form of material. All other defined character positions contain either a defined code or a fill character ( | ). The fill character is used in a defined character position when the cataloging agency makes no attempt to code the character position.
In all cases, field 006 positions /01-17 relate to positions /18-34 in one of the field 008 configurations. The relationship between field 006/00 (Form of material) codes and field 008 configurations is listed in 006/00 (Form of material).
