Fields 001-006 contain control numbers and other control and coded information that are used in processing MARC bibliographic records.

Variable control fields contain neither indicator positions nor subfield codes.

006 - FIXED-LENGTH DATA ELEMENTS--ADDITIONAL MATERIAL CHARACTERISTICS--GENERAL INFORMATION (R)


This field 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. It is also used to record the coded serial aspects of nontextual serials.

The field has a 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, character positions 18-34. Configurations of field 006 are given in the following order: books, computer file, map, music, serials, visual material, and mixed material.
