A record is determined to be a book if it meets the following criteria in the 000 leader field: (character 6 = a or t) AND (char 7  = a, c, d, or m). If this takes place, then in the 008 field, a record is created using the BK definition. In no place does it say ‘BK’. That’s not a possible code. See this documentation for details. Once the cataloger enters the requisite configuration in the leader 000 field, when they go to the 008 field, they will receive options only for possible book details (see screen shot below from the Cataloger's Reference Shelf documentation). 

Example code: 

SELECT instance_id, field, substring(sm."content", 36, 2) AS "language"

FROM folio_source_record.marc__t AS sm

WHERE field = '008' AND instance_id = 'a1dda667-0d5e-40a6-913c-08b1e26eba85'

;

The results screenshot below (Table 3) contains a row of data from the marc table where the 000 leader field shows that the material is a book (see Table 2, row 5) .  In the 008 field, if the material is a book, the characters 35 and 36 describe the language of the book (spaces 36 and 37). Looking at the this row which contains data for the 008 field in spaces 36 and 37, we see that the book is in 'EN' (English).

This field is used for information about special aspects of the item being cataloged that cannot be coded in field 008. Table 4 below shows a row of data of the 006 field where the 000 leader field indicates it is a computer file. In the screen shot below, the first two spaces identify the 1st space (character 00) in the 'content' column of the 006 field identifies 'form of material' . Referring to the documentationthe documentation for the 006 field (under 'Field Definition and Scope'), ‘m’ indicates Computer file/Electronic resource. This is the same as for field 008. Everything in 006 appears in the same order as 008, as this is sort of an ‘annex’ field for 008 information.Table 4 below shows a row of data of the 006 field where the 000 field indiocates it is a computer file. The  

In Table 4 below, the ‘o’ in the 6^th space indicates ‘online’, and the ‘d’ in the 9^th space indicates that the computer file type is a document. This is based on the 006 field documentation for ‘computer files’. Looking under 'Computer files/Electronic Resources' in the 006 documentation, we see that the 6th character describes the 'Form of item' and the 9th character describes 'type of compter file'.  However, for possible values for form of item/material, we need to look at the documentation for the 008 field, where we see that for a computer file, when the form of item ='o'  , it is an online material. Note that the 008 field contains information for the form of item/material in character 23. Everything in 006 appears in the same order as 008 but not in the same charcter spaces. The 006 field is a sort of  ‘appendix’ field for 008 information.
