Leader/17 Encoding level

Character position definition and scope:

The Encoding level character position contains a one-character code that indicates the level of specificity of the holdings statement. Codes 1, 2, 3, and 4 reflect the requirements of Levels 1, 2, 3, and 4 of Holdings Statements for Bibliographic Items (ANSI/NISO Z39.71) (formerly Serial Holdings Statements (ANSI Z39.44) and Holdings Statements for Non-Serial Items (ANSI/NISO Z39.57)) and codes 1, 2, and 3 reflect the requirements of Levels 1, 2, and 3 of Holdings Statements--Summary Level (ISO 10324). The MARC content designators given in the description of each Holdings level are the ones required by Z39.71. Optional data elements for each level are not mentioned here; they are given in each standard. A single-part item holdings statement is normally recorded at level 1. A multipart or serial item holdings statement may be recorded at any level.

When holdings information is embedded in a MARC bibliographic record, the Leader/17 code may be contained in subfield $e (Encoding level) of field 841 (Holdings Coded Data Values), which is also embedded in the bibliographic record.
