Can you advise how to merge marc records?
If you think that your records could be better quality by comparing it to what we have, you can do an Alliance Recon. Go to Catalog Tab, Update Titles, and Recon Subtab. You can always do the default of only brief records since these do not have any subjects in the record. However, if you do the All library records, any subjects that you have entered that are not in the 690s fields will be replaced be what we have on file. Ours are usually better unless there is a dedicated cataloger that puts in special subjects for your curriculum.
Next create a resource list called duplicates.
After that you can see what records have duplicate standard numbers which is a good start. Go to Catalog Tab, Update Titles, and Recon Subtab to find the titles. View the titles that were found and add them to the Duplicates resource list. (You can go back and forth to the report easily be clicking on the Job Summary breadcrumb that is under the word Catalog in the Tab menu.)
After you are done, go to the resource list and select Duplicated title for each entry of one of the titles. Select View these Duplicates from the I want to dropdown menu. Choose which is the best title and click merge. You can then remove this title from the resource list and go to the next one.
If you come across any titles that are duplicates that may have different standard numbers, just add them to the Duplicates resource list.
