An extensive listing of all batch jobs at Columbia and Cornell exists in the Batch Inventory spreadsheet and there are links to detailed process descriptions in the Outline. One of the fundamental differences in the use of MARC records for approval receipts is that Columbia creates Purchase orders and line items as part of the load whereas Cornell loads only Bib bib and Holdings holdings records. Reports of each load arrive as emails to acquisitions staff. Duplicates that are detected via ISBN matching are manually resolved by an MPS supervisor and records are merged. Frequently this requires the deletion and recreation of line items in order to delete the duplicate record. Columbia uses Voyager operators named with the Vendor Code vendor code to display in the history as the creators of the bibliographic and holdings records. Approval items load with the default "sho" locations. Shelf ready approvals load with locations and items, a report of item barcodes is sent to acquisitions staff who scan them as soon as possible to ensure the OPAC reads "In transit to library" rather than "Not checked out".

Export of Columbia's records to OCLC takes place every Wednesday for records last edited in the week 10 days before export (it is assumed all edits are by then complete). Cornell sends a nightly export of new cataloging which are triggered by a cataloging statistic in the 948 field. OCLC keys are added as 035 fields from a return report for both libraries. Columbia sends a separate file for East Asian titles as they also load institutional records. Many record sets have a 965 marker that serves to enable easy selection and collection identification and to apply the policy of not uploading certain Eresource eresource collections to OCLC. Cornell uses an 899 field for aggregating vendor packages and a 995 field to prevent export. Columbia excludes from export EL 5 preliminary records processed for Precat/Offprecat while Cornell includes records with EL 3, 5 and 8 in its uploads.
