Purpose of the list The purpose of the Superseded List is to assist selective depository documents librarians in disposing of superseded materials. The materials listed in this publication may be discarded before the normal 5-year retention period for non-superseded materials, without submitting them on a weeding list for Regional library approval. Background This year 2000 Web Supersed List unpdates the 1996 print edition. That 1996 edition was the second to be issued as a separate publication, updating the 1992 edition. The 1984 and 1986 editions appeared as Appendix C to the Instructions to Depository Libraries. The 1996 list, like the earlier versions, was prepared by the members of the Superseded Documents Committee, who volunteered to revise individual sections.
