Matching Guidelines #
Must match, except for the following cases: If there is a 1st edition statement in the record but not in the book or vice versa, the item may still be considered a match. A book club edition statement may be ignored. A library edition statement may be ignored.
Repeating the 250 Field #
When a single bibliographic record is shared between formats that match based on the guidelines set in this procedures guide, the 250 edition statement may be repeated if both statements are present.
250 __ First hardcover edition.
250 __ First trade paperback edition.Variations in the edition statement (250) #
Trade paperback editions #
Trade paperbacks are often able to share records with hardcover books if the only difference in the edition statement is the binding form, i.e. a first edition hardcover and a first trade paperback edition may be considered a match. However, mass-market paperbacks seldom can be attached to a record for a hardcover copy due to other variances.
Book club editions #
You can attach a Book Club edition to a record for a regular edition if the edition statement is the only difference. If the ISBN for the Book Club edition is not present on the record, the local Cat1 cataloger should add another 020 field.
Library editions #
You can attach a library edition to a record for a regular edition if the edition statement is the only difference. If the ISBN for the library edition is not present on the record, the local Cat1 cataloger should add another 020 field.
Audiobooks #
Library edition audiobooks are usually identical to the trade edition except for the ISBN and possibly the publisher number and packaging. In some cases they may also have library edition statements. The edition statement can be ignored, if the extent and contents of the items are the same–including number of discs, time, and narrator.
There is usually a more favorable replacement policy for library edition audiobooks, so it is recommended that item notes be used if you need to denote which edition your library owns.
A trade edition for an audiobook may be attached to a record for a library edition if everything else on the record matches the item in hand. A library edition audiobook may likewise be attached to a record for a trade edition.
If all other criteria match and you attach your audiobook, check to make sure the ISBN and publisher number (028 field) for your item appear on the record. If necessary, the local Cat1 cataloger should add this information.
Numbered and named editions #
If there is a 1st edition statement in the record but none is found in or on the item or vice versa, the item may still be considered a match if the missing edition statement is the only difference.
If a first edition statement on the record or item specifies a geographic location (such as First US edition, First American edition, or First North American edition), it should still be considered a match, as long as the place of publication aligns with the edition statement and no other differences exist.
For any other numbered (3rd, 5th, 18th, etc.) or specially defined (Revised, extended, large print, director’s, widescreen, etc.) edition, it is not a match.
Rental editions #
You can attach a rental edition of AV material to a record for a regular edition if the edition statement is the only difference. If the ISBN/UPC for the rental edition is not present on the record, the local Cat1 cataloger should add another 020 field.
NOTE: Watch carefully for missing special features and alternate language tracks on rental editions which require the materials to be placed on a separate record.
Rental editions of videodiscs #
Rental editions of videodiscs may be added to a record for either a combo pack or individually released non-rental edition records if all the content matches. Catalogers should pay close attention to special features and language options in determining whether a new record is needed. If the content is identical, catalogers may add their item and include information unique to their item such as ISBN, UPC and/or publisher number to the existing record. For ISBN or UPC fields, catalogers should indicate that the information was taken from a rental edition by including a qualifying information subfield:
020 __ ‡a 9780061435164 ‡q (rental edition)Retain the edition statement if it is already present in the record, even if it does not match your item.
