The Technical Note on page 3 of the September-October 1997 Technical Bulletin announced a change in format to the Secondary Source Identifier (SI) Field in GenBank records from six characters to eight characters as of spring 1997. This should have stated that new records coming into the database as of spring 1997 will contain an eight character value in the SI field. Older records will retain their original six character value.
