The last book in Australia? Importing last Australian copy holdings into Millennium Christian West University of Canberra christian.west@canberra.edu.au
Background: Large-scale deselection project Not routinely checking on LibAus before deleting Potential to be removing items of significance
Method: Request a file of unique holdings in Australia from LibrariesAustralia Match this against all Millennium holdings Upload a note into all bib records to indicate these are the last copy
Requesting a file: Contacted LibrariesAustralia and requested a file of our unique holdings in Australia and our unique holdings in the ACT File format: Pipe delimited with 001, 245, 100 and 020 Provided multiple Excel files (xls capped at 65536 rows, xlsx capped at 1048576 rows)
Extracting from Millennium: Create List containing all bib records, excluding e-resources tagged “local”. Didn’t exclude any other records as these were found in cleanup Exported 0191|a, 245, 100, 020 and the bib number
Matching: Used Python programming language Logic: If 001is the same as local 0191|a, match If 245 is 97% or higher similarity, match Else, no match Output: 001,100,245,bib number
Importing: Removed non-matches from the file for manual examination Converted Excel results into MaRC file using MarcEdit. Each record contains LDR (auto-created), 0191|a, 245|a, 907|a(bib number) and 988|aLast copy in Australia Load profile created which matches on bib number. Ignores most fields, matches on bib number and imports the 019 and 988 fields.
Deselection: Deselection lists are imported into Create Lists Before items are deleted, a Create List pulls out items that are the last copy in Australia These are put aside to be re-assessed
Lessons learned: Ask for more match points Title is an awful match-point We have the capacity to do this on a regular basis
