Identifying Midwest Tape On Order Records

WYLD Cataloging Technote : Identifying Midwest Tape Order Records

Order records are not intended to be a permanent record that is retained in WYLD. It is the responsibility of the ordering library to merge duplicate order records to the more complete record.

Order records from Midwest Tape

On order records from Midwest Tape cause duplicate bibliographic records just as other on order records do.  Midwest Tape provides order records for AV materials, both video recordings and sound recordings.

Midwest Tape order records for sound recordings can be identified by the 001 tag which begins with an upper case “MWT” before the number. Example: MWT11714506

The 003 tag for Data source will also have MWT but with no number following it.

Another identifier is that the 040 tag for Cataloging source contains the word “Midwest”.

Example of the Midwest Tape order record for a sound recording:

Midwest Tape order records for video recordings can be identified by the 003 tag for Data source which has MWT by itself as the sound recording records do. The 001 tag of the video recording order record has an OCLC number in the 001 tag.

Another identifier is that the 040 tag for Cataloging source contains the word “Midwest”.

An example of this is shown below.

These Midwest Tape order records for sound recordings and video recordings may look like more complete bibliographic records than other order records do. However, unless they have been edited, the records will provide only minimal subject access since they do not have valid Library of Congress subject headings (those 650 tags with a second indicator of zero or one).

These order records have an ISBN (020 tag) that may also be on another record in WYLD. Unless that ISBN is the title control number in the Control tab, the incoming order record won’t find the existing WYLD record so a duplicate bib record is created.

When the item is received by the ordering library, that library should search WYLD thoroughly enough to determine if there are duplicate bib records for that title. A search on title and/or ISBN will reveal the duplicate records. 

Order records are not intended to be the permanent record that is retained in WYLD. It is the responsibility of the ordering library to transfer their items to a more complete record or to overlay on order records with a more complete record. If other libraries have added holdings to the order record, this duplicate record should be reported to the WYLD Office so the duplicate records can be merged. However, if the ordering library has the only holdings on the order record, that library can transfer its holdings to the more complete record without contacting the WYLD Office. The transfer process will automatically delete the order record when the order holding is transferred to the fuller record. Instructions to transfer holdings can be found in the Cataloging Technotes.

If help is needed with this process, contact the WYLD Database Manager.

The library should change its order call number and dummy barcode to its actual holdings information on the more complete bib record. Edit the order call number; do not create a new holding while leaving the xx call number still on the bib record.
