MARS 2.0 processing determines the format of the record based entirely off of the values of leader bytes 06 &amp; 07. The value for LDR 06 must be met before the value for LDR 07 is even considered. So, if LDR 06 byte value is '''e''', yet LDR 07 byte value is '''i''', the record will still be considered a map (MP), even though LDR 07 says it could be a continuing resource (CR).

          <rev contentformat="text/x-wiki" contentmodel="wikitext" xml:space="preserve">In conjunction with the Library of Congress announcement that the 440 tag will no longer be standard, many clients have wondered what this will mean for our standard series processing. This series chart shows you exactly how each 4XX series tag will act based on it being matched, unmatched, matched and traced or untraced and so on. Please let your Project Manager know whether you prefer this current standard series processing.

This table describes how 440 series tags are handled under the new LC standard.
