Browse index not updated when brief record is overlayed with the full record

• Article Type: General
• Product: Aleph

Description:
The OCLC record imported by a cataloger which will overlay the ACQ record does not normailze to the CAT's OCLC record data. An example; even though the title 24510 are exactly the same except the ACQ record is ALL CAPPED and the CAT record data is a proper case, the ALL CAPPED takes priority.

Resolution:
What you are seeing is the result of the way ALEPH does index updating. The original title is indexed in all uppercase, and this is how it will appear. Then, when you overlay the record, the title is replaced by the new, mixed-case form of the title. However, the internal representation of the title (for correct filing purposes) has been normalized to a form that ignores case. So when the new form is compared to the old form, they are exactly the same (in their normalized form). Consequently, the system doesn't see a need to update the index entry. This occurs only when the only difference is case.

This is not associated with OCLC in any specific way. You will see this same behavior if you do this, as a test. Create a record with the title 'THIS IS A TEST TITLE'. The browse index will show 'THIS IS A TEST TITLE'. Now update the tile to 'This is a test title'. The browse index will continue to show 'THIS IS A TEST TITLE'. Now if you change 'This is a test title' to ''This is just a test title'', save the record, change it back to 'This is a test title', and save it again, you will see it in mixed case.

There are a few ways to deal with this problem:

1) The standard way is to search the title index in the Cataloging client. Find the title in all upper case. Highlight the title. Click on the 'Correct Display' button on the right. Overtype the all upper case version with the mixed case and save it.

2) Make any change to the title in the Cataloging client, save the heading, and then change it back and save it again.

3) When you create the ACQ record, don't use all upper case (or if you are using a supplier for these records, ask them to use standard mixed case titles.)
