--- Comment #13 from John Sterbenz <jsterben at umich.edu> ---
Bibliographic Level and Type of Record are both stored in the MARC record
"Leader"--the first 24 characters of any MARC (bibliographic) record.  Leader
Byte 06 is Type and Leader Byte 07 is Bibliographic Level (note that counting
in the Leader starts with 0).  Though they are not stored in the 008, they work
together to determine the rest of the fixed fields to be used in any given
record.  Other fixed field values are also incorporated into the Leader and not
the 008 (including Encoding Level and Description).

OCLC's Bib Formats and Standards contains useful information here (Bib Formats
and Standards is free for use and is NOT restricted to OCLC member libraries):

Fixed field overview (includes discussion of the Leader and 008 values that are
always in the same place, regardless of format):

Type of Record (has a nice table showing the relationships between formats,
Type, and Bib Level):
