To merge two bib records, you must first merge the item records
from the old to the new. Horizon will not allow you to merge the item
record/copy record/bib record in one step. (It will allow the overlay of a bib
record from OCLC.)
- Relink each item. This can be done as a batch process if there are
multiple items to a bib record.
- highlight the item(s) to be moved to the new record
- click on Bib on the tool bar
- click on Relink Items

- Note that Horizon will ask if you want the items connected to a specific
Copy record if there is one in the new record. If you are relinking multiple
items, create a copy record in the new bib before completing the relink
function.
- After the relink function is complete, and if there are multiple items
involved, perform the following steps:
- delete the Summary of Holdings record … noting its contents.
- delete the Copy Holding record.
- delete the now empty bib record.
- In the new bib record, if multiple items are involved,
- create a new Copy Holdings record, if you have not already done so.
- create a new Summary of Holdings record, using the information copied from
the one you deleted in step 2.
