Series Processing Table

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.
