Variable data fields
The fields of variable length follow the record label. They hold control information and the bibliographic elements of the record.
Every field consists of:
- field number (3 bytes)
- indicator (1 byte)
- data (variable length)
- field terminator (2 bytes)
The field number is given in decimal, except for the holdings and local data fields. Those begin with a letter followed by a two-digit number.
The indicator is represented by a blank or a lower-case letter after the field number.
Every record is closed with the field terminator, which consists of the two ASCII characters 13 and 10, that is CR LF.
