[Evergreen-catalogers] Batch deleting MARCs

[Katie Greenleaf Martin]

What we have started doing with econtent records is to create a new record match set so that they match on the 037 (provider ID) as opposed to ISBN. We made sure that we had the Hoopla ones all separated from other econtent records, and so now when we have the delete file, we can import it to match on the 037 and overlay the record with the URIs with the record from Hoopla’s deleted records file. Then, because the updated records have no URIs, we can put them in a bucket from the import queue and delete them all at once.

I’m not sure if this would work with all providers, since we only manage Hoopla records centrally (since it’s the same batches for all of our members who subscribe), but it has been helping us do that management since we implemented it this summer.

I’m happy to provide more details 😊

Just like Ruth, we have also gone to a discovery layer, but ours pulls everything from Hoopla through an API, except music records, so it's much less work than it used to be.

The monthly deletions spreadsheet from Hoopla contains a list of urls.  I use a text editor to format these urls into a SQL statement so I can get a list of the record ids from our system.

Something like this:

select distinct(record)
from asset.call_number
join asset.uri_call_number_map ucnm on ucnm.call_number = call_number.id
join asset.uri on uri.id = ucnm.uri
where (
 uri.href = 'https://www.hoopladigital.com/title/11780681' or
 uri.href = 'https://www.hoopladigital.com/title/12326359' or
 uri.href = 'https://www.hoopladigital.com/title/16968789'
)

Once I have this list, I export the records from Evergreen and remove the 856s using marcedit.  I then reimport them and send the records to a bucket so they can be deleted.

Hello cataloguing friends!
We're looking at including Hoopla and possibly other digital records in our catalogue, but don't want to do so until we find a way to batch delete or automate the deletion of records for titles we no longer have access to.
We currently have cloudLibrary MARCs in our database, and then every month we have to manually search and delete records for titles we no longer have by first deleting an 856 field, then delete the bib.  Given the quantity of records we'd have from Hoopla, this workflow wouldn't be feasible.
My question is, how do you handle the maintenance of your digital records, and is there a way to batch delete bibs from either mrc. or csv files?

Appreciate your thoughts,
Tricia
