1. DEEP IMPACT METADATA & SUNCAT Natasha Aburrow-Jones

2. Introduction to SUNCAT SUNCAT: the Serials Union Catalogue for the UK Project started in 2003; service launched in 2005 – and still going strong! 100 Contributing Libraries – National, University, Specialist

3. How we accept data - carrier MARC Communications Format files ftp’d to a secure area on the SUNCAT server (preferred) WORD Documents Excel spreadsheets Access databases csv / tab_separated files Anything (everything) else

4. How we accept data - content AACR2 RDA Hybrid Anything (everything) else

5. Data normalisation For all libraries, some standard normalisation, e.g., Change in tag 022 lower case “x” to upper case “X” Change 245$h[computer file] to $h[electronic resource] Change 6XX$xPeriodicals to $vPeriodicals only when it is the last subfield in the tag

6. Data normalisation - tailored Bib. data and holdings are tailored for each library, e.g.: Transfer 930$y to 852$b Transfer 930$m to 852$3 Transfer 930$1 to 852$h If the 022 tag is not in the format of 4 digits dash 4 digits, then reformat

12. Impact of (non)-use of data standards Lack of consistency across records Not matching with other records due to paucity of data / different data used to describe the same item Multiple records in the same library catalogued differently Data not homogenous even within one library catalogue, let alone the 100 in SUNCAT

14. Existing matching algorithm Based on that originally used by the California Digital Library Adapted by SUNCAT to include extra MARC fields Points based Weighted to have non-matches rather than mis-matches Good for standardised materials

15. New matching algorithm

16. Conclusions It would be much simpler if everyone followed the existing standards, whether that be for content or carrier! BUT – that’s not going to happen. So, we know that we’ll have to keep on trying to standardise the non- standard. The joys of cataloguing in a shared environment!
