+====== 007 field ======
+The 007, the physical description fixed field, is a variable control field used to define elements of the resource not included in the Leader/008. While OCLC uses subfields for elements in the 007, MARC 21 defines the elements by position. Codes differ dependent on the format of the resource. Traditionally used for non-print formats, more recently coding has been added to the 007 field for print resources.
