1	Library of Congress scenario: contributing to the DLF digital registry Rebecca Guenther Library of Congress rgue@loc.gov
2	LC environment Single record cataloging approach: MARC records in ILS for analog item with 856 link to digitized version Record to be identified by local field flagging it to be pulled ILS record needs to be distributed through regular channels and remain intact Need to extract portions of record and add digital registry elements so it reflects digitized version only
3	Workflow Phase I: English language monographs Export selected records (using local flag) in MARC 2709 Convert batch to MARCXML using LC tool Add digital registry elements (from “cookbook”) using XSLT stylesheet
4	Batch revision of records 001 (control number), 003 (institution), 005 (update date/time) 007/11 (antecedent/source): generate on basis of project to indicate original from which item derived 007/13 = p (reformatting quality: preservation) 008/23 = s (form of item:electronic)
5	Batch revision (cont.) Add 042 (Authentication code)= dlr Add 533 (Reproduction note): Electronic reproduction. Washington, Library of Congress. Add 538 = Master and use copy Add 776 (link to original) $a original $w [control number] Revise 856 to include only URL and change indicator designating relationship
6	Batch revision (cont.) Strip fields 010, 007, etc. Convert from MARCXML to MARC 2709 Contribute to registry in batch when available Resulting records added to registry, but these are not the official LC distributed records Updates to original record need to trigger a revised registry record
