1. The Z00T “View record history” (rep_ver version 20) EPUG-UKI Conference 2010 British Library, Nov. 1-2
Yoel Kortick

2. What is this?
The new “View record history” feature allows the staff user to see when a record was changed, by which user, and what was changed
This differs from the existing “view record’s catalogers” option because “view record’s catalogers” does not show what was changed
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

3. Introduction part 1
Description: Catalog - Option for tracking updates of Bib records.
Every change in one of the predefined fields - /[bib library]/tab/tab_fix - of a Bibliographic catalog record will be recorded.
The system will be configured to keep track of up to 16 fields.
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

4. Introduction part 2
The following information will be recorded, per each changed field (which is a tracked field according to the predefined list), and be searchable:
The changed field tag
The field's original information (including all subfields)
The cataloging ID of the staff that cataloged the original information (before the change)
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

5. Introduction part 3
The history information that is recorded in the tracking table (Z00T) will be viewable using in the Cataloging GUI
This will be done by using a new 'Record History' window: 'Edit Actions' -> 'View Record History' menu item.
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

6. Implementation instructions part 1
Add the following lines to /[bib library]/tab/pc_tab_col.lng:
PC_CAT_TRACK L Cataloger C Cataloger
PC_CAT_TRACK L Field C Field
PC_CAT_TRACK L Filed Data C Filed Data
PC_CAT_TRACK L Date C Date
PC_CAT_TRACK L Hour C Hour
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

7. Implementation instructions part 2
Add the following lines to /[bib library]/tab/pc_tab_exp_field.lng
REC-HISTORY-SORT L Date and Time DATE-TIME
REC-HISTORY-SORT L Cataloger CATALOGER
REC-HISTORY-SORT L Field Code FIELD
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

8. Implementation instructions part 3
Add the following lines to /[bib library]/tab/tab_fix
INS2 fix_doc_track ##,245##
Column three may include additional (up to 16) fields to be tracked as well.
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

9. Implementation instructions part 4
Create new Oracle table Z00T in bib library:
util/A/17/1
TST01> grep -i Z00T $aleph_root/tab/file_list.BIB
TAB z00t 100K,128K,4M,128M,128K,128K 0K ts0,TS1D,TS2D,TS3D,TS1D,TS1D
IND z00t_id 100K,128K,4M,4M,128K,128K 0K ts1,TS1X,TS2X,TS2X,TS1X,TS1X
TST01>

10. The Z00T Oracle table
Here is a case where the bibliographic record has been updated
First the 1001 field was “Hessen, Edith van.”
Then it was “Hessen, Edith Van Dyke”
Finally it was “Hessen, Edith Van Dyke$$d1971-”
select Z00T_TEXT,Z00T_UPDATE_DATE,Z00T_CATALOGER 2 from Z00T 3 where Z00T_REC_KEY = ' ' and Z00T_FIELD_CODE = '1001‘ 4 order by Z00T_UPDATE_DATE;
$$aHessen, Edith van BENTZI $$aHessen, Edith Van Dyke MASTER $$aHessen, Edith Van Dyke$$d HERRING
3 rows selected.

11. Viewing the history In the GUI The user does as follows:
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

12. Viewing the history
And now the user can see 1001 the fields as they changed
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

13. Making a test
In tab_fix we have added field 690 to column three for field 690
INS2 fix_doc_track ##,245##,690
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

14. Making a test part 1 User OZ logs in and changes 690 $$aBooks to
690 $$aBooks and magazines
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

15. Making a test part 2 User LILACH logs in and changes
690 $$aBooks and Magazines to
690 $$aBooks and serials
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

16. Making a test part 3 User BENTZI logs in and changes the
690 $$aBooks and serials to
690 $$aBooks and journals
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

17. Making a test part 4 User GEFEN logs in and changes the
690 $$aBooks and journals to
690 $$aBooks and journals (print and on-line)
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

18. The results Menu “view record history” now shows this
Unlike our competitors, we did not release a new revolutionized system every few years but rather took the evolutionary approach

19. The results And here is the Z00T oracle table
select Z00T_TEXT,Z00T_UPDATE_DATE,Z00T_CATALOGER 2 from Z00T 3 where Z00T_REC_KEY = ' ' and Z00T_FIELD_CODE = '690‘ 4 order by Z00T_CATALOGER; $$aBooks and journals BENTZI $$aBooks and serials LILACH $$aBooks and magazines MASTER $$aBooks MASTER $$aBooks and magazines OZ 5 rows selected.
