The most significant changes in Update 8 are those for computer files.  The change in the definition for the Type of Record leader code for computer files (code m) led to a change in the arrangement of fixed fields for most computer file serials.  "Fixed Length Fields - General Information" and "Type of Record (Leader/06)" were revised to reflect this change.  Field 856, "Electronic Location and Access," includes new indicator values and subfields.  Field 530 and Appendix N, "Special Physical Formats," were also revised to reflect these changes.
