Added Copy or Edition? How to Decide

I. General information

I. Use these guidelines to make local decisions on treating new materials as added copies (duplicates) or as separately cataloged, different editions in cases where the same title is already in the Library's collection. Compare the new work in hand with the information shown in our local cataloging record for the already existing title we own. Decisions on whether or not to use a given OCLC record are governed by detailed guidelines in OCLC's Bibliographic Formats and Standards

If you have determined that the item in hand is an added copy, make a new item record for the added copy and put “2” in the Copy Number field. Link the new item record to the existing holdings record.

II. Specific Guidelines

An item is an added copy/duplicate to an existing title if the bibliographic description of the first one cataloged fits the new item acquired in all major aspects. Listed below are the areas which should be examined when making the added copy/different edition decision. One or more important variations in these areas normally indicates that a separate record should be created for the new item.

Author. Do not treat as a different edition on the basis of different choice or form of entry in the record.

Title. Do not treat as a different edition because of differences in judgment as to what constitutes title vs. subtitle information or differences resulting from use of cover title information vs. title page information. However, a difference in actual wording of title or subtitle may indicate that material has been revised.

Edition statement, if any (can appear in the description or in a note). Some publishers, notably Latin American, Spanish, Portuguese, and German ones, often use the word “edition” (e.g., “edicion”, etc.) to mean printing. A true new edition may often be distinguished, in such cases, by the use of additional terms such as “revised,” “enlarged,” “corrected,” etc. Note that, in some cases we own several other editions of the same title. When edition statements differ, check to see if any more appropriate catalog record is in our catalog, and if not, check OCLC.

Place of publication and publisher. Treat as the same edition if the publisher is the same, and if any one place named on the item matches one given in the description. In the case of multiple publishers, treat as the same edition if any publisher named in the item matches one given in the cataloging description. If the publisher is different (not just form or completeness of the publisher name, or name of parent company vs. name of its subsidiary), treat as a different edition.

Note: In some cases the book in hand names more than one place of publication and/or publisher, but no corresponding place/publisher appears in the catalog record. In other cases, the book names only one place/publisher and the catalog record a different place/publisher, but the book matches the rest of the catalog record. In both cases, the book already in the stacks should be checked to see if places/publishers not shown in the catalog record are listed in the book, keeping in mind the “one in the item matches one in the catalog description” criterion for treating the newly acquired book as an added copy. If the books turn out to be identical after all, revise the catalog record to show accurate information (e.g., two publishers), or find a record that matches them better (with a publisher that both books have in common).

Distributor. Do not treat as a different edition on the basis of presence or absence of distributor information or difference in name of distributor.

Date. Do not treat as a different edition on the basis of differences in printing date or manufacture date in the case of photocopies added to photocopies, unless the particular printing contains textual variations as indicated by phrases such as “Reprinted 1982 with corrections,” or “2nd revised printing,” or you have a reprint by a different publisher. Do not treat copyright renewal as a different date unless accompanied by other changes in the work.

Format. Treat as the same edition only if the format of the item in hand is the same as the item represented on the existing catalog record, e.g. add microfilm items only to microfilm records; do not add photocopies to records for the original or vice versa. See Part III, below, for special instructions for paperback editions.

Physical description. Do not treat as a different edition on the basis of minor variations in physical description such as presence or absence of illustration statement. Do watch for presence or absence of special illustration statements, such as “Extra illustrated edition,” differences between multi-volume vs. single volume editions, etc. Check the last page or so of the work in hand; sometimes an “afterword” or addendum or supplement of just a page or two has been added to the original, creating a true new edition. Size differences between paperback and hardcover editions should be disregarded.

Accompanying material. Watch for differences in accompanying material, but do not treat as different edition on the basis of presence or absence of an accompanying material statement in the record.

Series statement. Do not treat as a different edition solely on the basis of the form of the series statement, or presence or absence of a series statement in the record or on the piece. To be treated as a different edition, there must be a totally new series associated with the piece.

Language of the text. Treat translations, simultaneous publications in different languages, etc., as different editions.

Name of editor, translator, illustrator. Treat as a different edition if the item has a different editor, translator, or illustrator; if information present on the item is lacking in the record, compare the item in hand with the previously cataloged item.

Contents note. Do not treat as a different edition on the basis of the presence or absence of a contents note in the record, but watch for major variations in content of the volume(s).

Other notes. Watch for notes in the existing record or information in the newly acquired volume indicating differences in content, which normally require treatment as a different edition. Indications of limited, numbered, or autographed editions/copies, whether in the volume or in the existing record, do not in themselves justify cataloging as a new edition.

III. Additional information for paperbacks

A common problem in deciding whether or not to treat an item as an added copy to a title already in the collection involves paperback editions of works the Library owns in hardcover edition, or vice versa. Apply the following guidelines in dealing with the special case of paperback editions:

A. Treat the paperback edition as an added copy if the only differences from the hardcover edition are:

  1. Size
  2. Presence of a paperback publisher's series
  3. Presence of a statement such as "first paperback edition"
  4. Renewed copyright; no new material added to the work
  5. ISBN (hardcover vs. paperback ISBN).

B. Treat the paperback edition as a different edition if the differences include:

 1. Significant differences in pagination
 2. Significant differences in edition statement (not just "paperback edition"
 3. Significant differences in series statement (i.e. a totally different series)
 4. New copyright, when edition includes new material (such as a new introduction, a supplement, or a postscript).
