Introduction
Overview
Purpose
Issues
Pros and Cons
Conclusion
Overview Transition of cataloging practice for Korean
scripts Integration of RLIN records into OCLC WorldCat Proposal to change the CONSER policy on
transcription of Korean characters to include spaces between words
Discussion regarding the spacing issues RLIN cataloging practice: Input space between words OCLC cataloging practice: Input without space Input space as appears in the book
Purpose
Consistency
Standardization
Efficiency
User consideration
Two different cataloging practices regarding spaces
With Space
Without Space
Issues Display: Two different indexing records in library catalog
With space Without space
Retrieval: Technical issues for retrieval depending on the indexing system Only searchable as indexed in word search system: ex) Voyager Searchable regardless of space in character search system: ex)
Aleph
Other issues regarding Hancha Spacing in combined Hancha / Hangul Hancha / Hangul cross mapping
Pros and Cons
Space matters: Voyager & RLIN Relevant search result when searching for the exact
keyword or title as indexed No search result when searching for the keyword or
title with different spacing
Space doesn’t matter: Aleph & OCLC Consistent search result regardless of spaces Irrelevant search results or less relevant search
results due to character by character searching
Voyager: 국어문법 (without space) / 국어 문법 (with space)
국어문법 (without space) No Result
국어 문법 (with space) 20 Results
Voyager: 국어문법 (without space) / 국어 문법 (with space)
Indexed with spaces
Pros and Cons
Space matters: Voyager & RLIN Relevant search result when searching for the exact
keyword or title as indexed No search result when searching for the keyword or
title with different spacing
Space doesn’t matter: Aleph & OCLC Consistent search result regardless of spaces Irrelevant search results or less relevant search

Indexing issueConsistent, efficient and standard cataloging
practice based on users’ standpoint
Retrieval issueConsistent and relevant search results based
on user’s search behavior
