Overall vs. local
Local - needs - solutions

• Overall
• needs
• solutions

5
Subject indexing

• Overall level
• - UDC
• - LCSH
• - MeSH

• Local level (local keywords)
• - local classifications
• - local subject headings

6
Local level Problems

• - Variety in content
• - Variety in application
• - Only locally visible

7
Overall level Problems

• - Low rate of catalogued documents
• - Problematic interface

8
Other problems

• - Time-consuming for librarians
• - Overall solutions not flexible enough

9
Consequence

• Librarians
• choose local solutions

10
New policy

• with the same subject cataloging schemes
• - MeSH
• - LCSH
• - UDC

11
Why UDC?

• - Universal
• - Flexible
• - Faceted
• - Multilingual, customizable AF

Flexibility in use of UDC will be encouraged
12
The idea behind

• Virtual library shelves
• - Subject categories rather than subject terms
• - Less effort
• - Efficient subject-search

13
New Interface E-sources

• - Local input
• - Hidden UDC
• - Easily accessible

• growing conscious-ness of overall ánd local needs

The idea behind

• Combine the advantages of
• word system and classification

21
Important advantages

• - Easy search on words
• - Hierarchical overview of search terms
• - Multilingual potential
• - Faceted and flexible
• - Algorithm applicable to other KOS

22
Fine feathers

• dont make fine birds

23
Many other things to do

• - Further development of the interface
• - Update UDC authority file
• - Translation of UDC authority file

24
Parallel projects

• - Linking local subject methods to UDC
• - Linking shelf numbers to UDC
• - Experiments with (semi) automatic
  classification

25
New library system (Aleph 500)

• new perspectives
• - Stress on word search
• - UDC authority file gt UDC authority records
  (MARC21)
• - UDC hierarchy

26
Balance between local and global needs

• - Constant challenge
• - Essential for good service of our library
