6 Authority Control and Bib Enhancement with Marcive Mark Sandford William Paterson University sandfordm1@wpunj.edu

7 Cheng Library  Voyager 8.2  Approx 435,000 records  Over 100,000 Ebrary records  Authority control on creation, but not ongoing  Thousands of books withdrawn in the past 8 years  Inconsistent handling of problematic headings in Voyager batch processing of authorities  E.g. Name-title entries

8 Authority Control @ WPU  Initial contract with MARCIVE about 10 years ago  Regular incremental updates  Plan was to do full authority run every 10 years  Had heard of RDA-ification through MARCIVE marketing materials  It was time  Time was running out!

9 Our choices  Name Authority Files  LCSH Authority Files  MESH Authority Files  Additional processing  Addition of RDA CMC (33X fields)  Kept GMD (Just in case (in case of what?))  260 to 264 field*  Lexile, Accelerated Reader, Reading Counts (Curriculum Materials)  Convert relator codes to relator terms  Various cleanup/tidying of fields and normalization * Required update to our VUFind installation

10 Working with MARCIVE  Library Information Services and Cataloging completed 11 page profile  No custom processing was needed  A la carte options worth a look  Profile sent May 16  Bib file sent to MARCIVE June 5  No existing bibs should be changed as of this date!  June 9 confirmation email from MARCIVE with notification of 2 bad records in our file  June 11 test file received  June 12 approval sent to MARCIVE  June 19 processed MARC files available via FTP

11 Loading into Voyager  MARCIVE provides batches of 50,000 records  Voyager suggests loads of 10,000 per batch  MarcEdit to the rescue  Already have Voyager 001s in records, so no complex matching needed  Start Loading!

12 Keyword Indexing (How NOT to import)  Pre Voyager 9.0 (we were on 8.2)  Default import performed keyword indexing  Generates a temporary index file  Each record loaded takes a tiny bit longer to load than previous record  If temporary file gets too large, the system crashes  Required nightly keyword index regeneration  Only 20k to 30k records per day loaded  1 example log showed 10k record loaded in 2 hours 14 minutes  The NEXT 10k took 4 hours

13 No Keyword Index (How to import)  Pre Voyager 9.0, Pbulkimport –X (NOKEY Disable keyword index and maintenance)  As of Voyager 9.0, this is the DEFAULT for Pbulkimport  Each batch of 10k took just under 1 hour  3 loads per day vs 8 per day  Single Keyword Regen at project completion

14 Authorities Records Loads  Decision was made not to wipe out existing authorities database  Voyager retains heading ids to match on – easy!  Also loaded in batches of 10k  Kept the –X switch, but no idea if it mattered

15 Result logs  In addition to the bib file, we received the following log files:  Reader notes report (for a small fee)  Unrecognized Headings for Corporate Names  Unrecognized Headings for Geographic Names  Unrecognized Headings for LCSH  Unrecognized Headings for Meeting Names  Unrecognized Headings for MESH  Unrecognized Headings for Personal Names  Unrecognized Headings for Series
