2. Aleph Shared Systems Models 2 ALEPH Shared System Models Bibliographic Data Administrative Data

3. Aleph Shared Systems Models 3 ALEPH Shared System Models – BIB data Bibliographic Data Multiple BIB records for same title, separate BIB record for each institution OR Single BIB record per title, BIB record shared by all institutions

4. Aleph Shared Systems Models 4 Administrative Data Single Administrative Unit (ADM) OR Multi ADM ALEPH Shared System Models – ADM data

5. Aleph Shared Systems Models 5 ALEPH Shared System Models – ADM data Single ADMMulti ADM Shared dataNon-shared data Shared circulationUniversal Borrowing/ILL

6. Aleph Shared Systems Models 6 BIB Record/ADM relationships Single BIB record per Title with Single shared ADM data Single BIB record per Title with Multi ADM data Multi BIB records + Union View (Virtually De-Duplicated Union Catalog) with Multi ADM data Separate Catalogs and a Union Catalog

7. Aleph Shared Systems Models 7 Single BIB record per Title with Single ADM BIB title BIB library ADM record ADM library

8. Aleph Shared Systems Models 8 Single BIB record per Title with Single ADM - Implications ALL institutions share a single BIB record Less Oracle table space is required for BIB data Shorter indexing time ALL institutions share a ADM data Enables shared circulation ADM configuration tables No institutional control Tables can be long Authorization/Permission setup are required in order to limit access control per institution

9. Aleph Shared Systems Models 9 Single BIB record per Title with Multi ADM libraries BIB record BIB library ADM Record ADM library ADM Record ADM library ADM Record ADM library

10. Aleph Shared Systems Models 10 Single BIB record per Title and Multi ADM - Implications ALL institutions share a single BIB record Less Oracle table space is required for BIB data Shorter indexing time Each institution controls its ADM data Universal Borrowing/ILL is required for sharing resources (circulation) ADM configuration tables Can be controlled by each institution (ADM library) Tables are of manageable length

11. Aleph Shared Systems Models 11 Virtually De-duplicated Union Catalog (Union View) with Multi ADM * Three copies of the same Bib record ADM Record ADM library BIB file BIB Record* ADM Record ADM library ADM Record ADM library

12. Aleph Shared Systems Models 12 Multiple BIB records per Title and Multi ADM – Implications Each institution controls its BIB data Multiple BIB records require More Oracle table space is required for BIB data Longer indexing time Virtually de-duplicated Union Catalog (Union View) for OPAC is desirable Each institution controls its ADM data Universal Borrowing/ILL is required for sharing resources (circulation) ADM configuration tables Can be controlled by each institution (ADM library) Tables are of manageable length

13. Aleph Shared Systems Models 13 Separate Catalogs and a Union Catalog BIB Record BIB Library Union Catalog ADM Record ADM library BIB Record BIB Library ADM Record ADM library BIB Record BIB Library ADM Record ADM library

14. Aleph Shared Systems Models 14 Separate Catalogs and a Union Catalog - Implications Enables multiple servers (per institution) Each institution controls its BIB data More Oracle table space (each BIB + Union) Virtually de-duplicated Union Catalog for OPAC is desirable Each institution controls its ADM data Universal Borrowing/ILL is required for sharing resources (circulation), and is facilitated by the Union Catalog ADM configuration tables are controlled by each institution (ADM library)

15. Aleph Shared Systems Models 15 Resource Sharing Single ADM Seamless shared circulation is inherent in a Single ADM PPH can be applied in a single ADM to enhance efficiency of materials transfer – time and distance Multi ADM on single server Enables shared patrons for walk-in services Achieved through ILL/UB* Multi ADM on multiple servers Achieved through ILL/UB* * ILL – library-to-library loan * UB – library-to-patron loan
