  4. 4. A brief history *Academic Services Information Librarians do the classification at the University of Bath*• Universal Decimal Classification adopted as alternative to Dewey• Updated schedules not purchased • New subjects not covered• Additions, notes and amendments made on schedules and, more recently, on the Library wiki • UDC numbers „disguised‟ as Dewey• In-house schedules for some subject areas• Negative student feedback• Possibility of shelf-ready
  5. 5. Task Group: formation & methodology • Communications Task Group recommended that: “the classification system and organisation of stock be reviewed with a view to implementing a system which is more consistent, user focused and intuitive.” . • Classification Policy Task Group formed Methodology: • Graduate Trainee report • Literature search • Ongoing projects • Costings (out-sourcing and in-house classification) • Available schemes and associated costs
  6. 6. Task Group: identifying optionsA. Maintain the status quo D. Outsourcing • Incur no additional costs • Any benefits? • But not practical E. Retro-conversionB. Which classification • Time consuming scheme? In-house or • Test area? commercial F. Management of • Ease of use essential retroconversion (students and staff!) • Outsourcing? • DDC or LCC • Large scale one-offC. Application of schedules project • Across the whole library • Test area
  7. 7. Task Group: conclusionsPreferred options• Adopt Dewey across the library • Update to latest editions when available• Use Coutts shelf-ready service• Retro-convert existing stock• Short term intensive retro-conversion projectAlternative options• Adopt Dewey on one floor • Update to latest editions when available• Use DDC classmark from downloaded BDZ records• Partial retro-conversion of identified problem areas
  8. 8. 2009 pilot project1. “To retroconvert architecture books within the 720 range in our UDC sequence to DDC.”2. “To acquire new architecture books likely to fall within the DDC 720 range in shelf-ready format.”• Dewey editions 19+ deemed acceptable• 7,108 items in 720 range• Using ISBNs Coutts found DDC numbers for 3,500• BDZ records for 3,118 had acceptable Deweys• Unmatched books to be classified in-house• Coutts chosen as shelf-ready supplier• Retro-conversion to be done in-house
  9. 9. Pilot project proceduresAcademic Services:• Check spreadsheet of titles: • DDC19+ numbers accepted without checking • DDC18 numbers checked and accepted or reclassified• Remaining 1,122 items transferred to storage area for classification from scratch • (issued to „RECLASS‟)• Holds placed on items out on loan• Joblink staff (aka students) produced spine labels and updated recordsTechnical Services:• Quality control items coming in as shelf-ready
  10. 10. Pilot project: results• Retro-conversion took 22 weeks• 6,768 items were reclassified• 340 books identified as missing (records deleted)• 1,068 moved outside 720 range• 67 architecture books ordered as shelf-ready (undercharged!)• Catalogue records enhanced• User feedback very positive
  11. 11. Expansion of the project• No use of shelf-ready• New books to Dewey using numbers in downloaded records• Extend to all of Level 3 (Mechanical, Chemical and Electrical Engineering)• Retro-convert all stock• Previous editions and extra copies • Huge amount of extra work for cataloguing• Early 2010 Request made for Management to be added (Level 5)• Late 2010 TS pushed for all fund codes to be Deweyed • Frustrating for the team to know items would be back • Still not literature…
  12. 12. Current Cataloguing procedures*Everything passing through Workroom now gets a Dewey number (except literature)*• Check record for a Dewey number• Check that it‟s a valid Dewey version for that fund code• If a number can‟t be found through BDZ, LoC or OCLC Classify it goes „upstairs‟ for a number• Returned to TS for final cataloguing and spine labeling• Extra copies & other editions • Extra copies dealt with by Technical Services • Other editions dealt with by Academic Services (partly because of Library layout!) • User IDs for Workroom and the AS floors for holds
  13. 13. Retro-conversion• Retro-conversion of Level 3 ongoing• Academic Services conduct targeted retro-conversion projects over summer vacation• Subjects/number ranges nominated by members of Task Group• Calculations of number of books and time needed to aid decision• Recent summer projects: • 2010 Mechanical Engineering (620s) • 2011 Computer Science (003-006) • 2012 nominations include: • Management (658 & 659) • Biology & Biochemistry (570s, particularly 571)
  14. 14. The future• Unlikely to adopt shelf-ready in the near future• Ongoing summer retro-conversion projects• Change to library layout?• Changes to Dewey…Keep going!As of January 17th 2012:32,151 titles in the library have Dewey numbers (13%)214,533 titles are still UDC (87%)Calculations predict another 17 years at the current rate..!
