The 6th column is for the use of regional depository libraries. An "R" in this column indicates those superseded titles that regional libraries have agreed to keep although they are not legally required under 44 U.S.C. Section 1911 to do so.

Titles which have become discontinued or inactive since 1992 are listed at the end of the main list.

Terminology

1. Discard if revised -- Keep the latest edition/issue of each title published in the series. This term is used for monographic series where each title in the series will have to be individually reviewed.

2. Keep latest edition/issue -- Only the latest edition or issue of the title needs to be kept. This term is used for series issued with some type of regularity.

3. Looseleaf. Discard pages if revised. Keep latest edition - Identifies looseleaf "manuals". Keep the latest edition of each title and the transmittals issued for that edition; revised pages may be discarded.

4. Periodicals/serials that are superseded by a cumulative edition are identified by a notation such as "monthly issues superseded by annual."

5. Some newsletters and announcements are listed with the notation "Keep current year plus previous year." These publications are generally from one to four pages in length and are of a current awareness nature.

6. Separates and reprints -- only those existing as of the June 1996 List of Classes are listed. Any title that is a "separate" or a reprint of an article appearing in a full issue of a journal or report may be considered as superseded. Before discarding any reprints, librarians should be aware that these items may prove useful for vertical file material, displays, handouts, or other promotional uses.

The following generic classes cannot be totally inclusive because of their broad coverage and repetitive nature:

- General Publications
- Handbooks, Manuals, Guides
- Regulations, Rules, Instructions
- Bibliographies and Lists of Publications
- Forms

Each title issued in any of the above series must be individually reviewed and may be discarded only when a revised edition has been received. Occasionally a single title from one of these general series is listed because it represents a title that is issued frequently or occupies considerable shelf space.

Only the Superintendent of Documents classification number used in the June 1996 List of Classes is listed. Each library should check its own records for previous or subsequent classification numbers for each series.

Below are listed some types of material which may be considered superseded and disposed of by all libraries according to Chapter 4, Maintenance, in the Instructions to Depository Libraries.

1. Any separates, slip opinions, slip laws, advance reports, etc., only on receipt of the bound volumes or cumulating issues or products.

Examples:

A. Daily Congressional Record, after bound volumes and index, or cumulative CD- ROM are received.

B. Slip laws, after bound Statutes at Large are received.

C. Slip opinions or advance reports, after bound volumes of United States Reports are received.

D. Any materials which are cumulated in later issues, i.e.:

Supplements to the United States Code, Internal Revenue Bulletin, etc., providing the library has selected the item number for the cumulative version and only after the cumulation is received.

E. Senate and House reports and documents, upon receipt of the bound Serial Set volumes.

F. Preprints such as the Minerals Yearbook are superseded by the annual bound volumes.

2. Reprints, provided the library has received the original edition. This original edition may be a government journal or a commercial journal, or any other source. If the library retains the original source, the reprints may be routed for current awareness purposes, entered into a vertical file, or simply treated as superseded documents. In this case, depositories are not obligated to maintain a shelflist, catalog, or otherwise keep records on these superseded materials as long as they have records for a permanent alternate source. If the reprint is the only copy retained by the library, standard bibliographic records must be maintained.

3. House and Senate bills and resolutions and legislative calendars one year after the adjournment of the Congress from which they originated.

4. Calendar of the House of Representatives. Retain Monday issues, then only the final issue of each session of Congress should be kept. Issues of the Senate Calendar may be disposed of one year after the adjournment of the Congress. The Senate Calendar is not cumulative.

5. Any publication upon receipt of a revised edition or an edition which states it supersedes. If a later edition is distributed through the Federal Depository Library Program or is otherwise available to the library, the superseded edition can be discarded by the library, even though that library has since deselected the item number and does not possess the new edition.

6. Pages from looseleaf publications that are replaced by new pages. 7. If a depository library has yet to receive a basic text or manual, then the transmittals, corrections, changes, errata, etc., to that depository disseminated publication can be considered superseded and discarded after one year.

8. Lists and indexes of publications of various agencies upon receipt of complete new editions. Small spot-lists, such as publication announcements, may be discarded 90 days after receipt.

9. Annual or biennial publications that merely revise information and bring it up to date, such as Index of Specifications and Standards, Light Lists, etc., upon receipt of a new issue. This permission does not apply to annual publications such as annual reports of departments and agencies, which cover the activities of the organization for a specific period of time.

10. Material that has an effective expiration date. Unless otherwise covered, materials such as press releases; dated posters; calendars; announcements of seminars, workshops, meetings or events; announcements of products or publications; and the like may be discarded after expiration of the event.

Some exceptions to number 10 are:

-- Civil Service examination announcements. Only the latest issues need be kept.

-- Commerce Business Daily may be discarded 90 days after its date of issuance; however, depositories should maintain the standard bibliographic records (e.g., shelflist, cataloging, serials check-in) that they use for other depository materials.

-- Navigation maps and Aeronautical charts that have passed their expiration date can be considered superseded and discarded. If not discarded, they should be clearly marked "Not for Navigation Purposes."

.Caution All depository librarians should note that this Superseded List does not require that materials be discarded. Do not dispose of any material that might be vital to the collection. Research libraries should be extremely cautious about weeding older editions and other items that are of historical or research value. Law libraries and medical libraries should also carefully evaluate any material in their respective disciplines. Every depository should carefully consider their particular needs and collection policy before discarding any material. When keeping superseded materials, it is important to mark them as "superseded" or "not current" because misinformation can be transmitted with outdated publications..
