Old Series Processing Table

Even though the Library of Congress announcement that the 440 tag should no longer be standard, many clients have wondered whether they can still have the older 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 older standard of series processing.
