## SICI and BICI:  Identifiers for Serials and Books

- Reference/Citation Linking: The Federal Perspective
- Joint CENDI/FLICC Workshop  June 21, 2000
- Library of Congress  Washington, DC
- Julia Blixrud, Association of Research Libraries and Chair, NISO Subcommittee AP

## SICI and BICI

- ANSI/NISO Z39.56-1996 (Version 2) -- Serial Item and Contribution Identifier (SICI)
- Book Item and Component Identifier (BICI) (being developed by NISO Subcommittee AP)

## SICI and BICI

- Background and Environment for Development
- Structure
- Applications
- Criticisms and Suggestions for Improvement
- Future Development

## The Challenges

- Need for increased granularity to identify intellectual units

- Need for interoperability and data exchange between different industries and applications using different computer systems

## SICI Background

- Version 1 development
- SISAC
- Specific application (fixed length)
- Version 2 development
- Before 5-year review
- Users identified possible new applications and problems with version 1

## SICI Development Goals 

- Z39.56 (1991)
- Cover broad range of serials regardless of physical format
- Short, but bibliographically unique
- Derivable from citation or source document -- not externally assigned or derived
- Maintain consistency with and build upon existing standards, e.g., ISSN

## SICI Development Goals 

- Z39.56 (1996)
- More rigorous rules relating to mandatory and optional fields
- Defined internal structure of SICI to have three distinct segments (Item, Contribution, Control)
- Defined external structure types to identify Serial Item vs. Serial Contribution (issue or article)
- Allows private numbering systems
- Stores/includes medium of distribution (text on paper, electronic, microform, etc.)
- Title code algorithm significantly improved -- length and inclusiveness

## SICI Structure -- CSI-1

- Item Segment
- ISSN
- Chronology
- Enumeration
- Contribution Segment
- [Empty -- required but will have no data]
- Control Segment
- Code Structure Identifier (CSI)
- Derivative Part Identifier (DPI)
- Medium Format Identifier (MFI)
- Version Number
- Check Character

- 1991 SICI:
- 0095-4403(199502/03)21:3;1-N
- 1996 SICI:
- 0095-4403(199502/03)21:3<>1.0.TX;2-Y

## SICI Structure -- CSI-2

- Item Segment
- ISSN
- Chronology
- Enumeration
- Contribution Segment
- Location (page)
- Title Code
- Alternative Numbering Schemes
- Control Segment
- Code Structure Identifier (CSI)
- Derivative Part Identifier (DPI)
- Medium Format Identifier (MFI)
- Version Number
- Check Character

## SICI Example -- CSI-2

- Bjorner, Susanne. “Who Are These Independent Information Brokers?” *Bulletin of the American Society for Information Science*, Feb-Mar. 1995, Vol. 21, no. 3, page 12
- 1991 SICI:
- 0095-4403(199502/03)21:3L.12:TII;1-N
- 1996 SICI:
- 0095-4403(199502/03)21:3<12:WATIIB>2.0.TX;2-J

## SICI Example -- CSI-3

- ERIC Document EJ 462 869, originally published in *Library Hi Tech*, Vol. 11, no. 1, 1993
- 1991 SICI:
- N/A
- 1996 SICI:
- 0737-8831(1993)11:1<::ERIC-EJ462869>3.0.TX;2-F

## SICI Applications

- SICI Bar Code
- EDI using SICI CSI-1
- Price/sales catalog
- Dispatch data
- Invoice
- Order
- Claim
- Claim Response

## SICI Applications

- URN Namespace
- Document Delivery
- Data string in delivery services
- Reference Linking
- Library catalog records to index or full-text databases

## SICI Criticisms

- Unicode
- Angle Brackets <>
- Title Code
- Sequencing
- Duplication (non-unique)

## SICI Future Development

- Five-year review scheduled for 2001
- Character set issues -- Unicode
- More explicit reference to electronic journals
- Explicit statement regarding DOI
- Structure changes (<> and *#)
- Integration with web applications

## BICI Background

- Begun in 1997 following completion of revision of SICI
- Develop standard identification schema for subunits of books
- Interest from rights management community
- International meetings on identifiers

## BICI Development: Background Documents 

- BIBLID
- SICI
- “A Standard Identifier for Book Items and Contributions” by David Martin for the Book Industry Communication (BIC) and the British National Bibliography Research Fund
- Work of INDECS

## BICI Development Goals 

- Limit scope of standard to code for unique identification of book items and their component parts
- Cover a broad range of books (scholarly, trade, and popular), regardless of physical form
- Maintain consistency with and build on the established ISBN already used successfully to identify books
- Create brief, unique code consistent with unique identification

## BICI Development

- Does not address grey literature, technical reports or other documents
- Does not address component parts that have no enumeration (unnumbered dictionary or encylopedia entries)
- Includes redundancies for judgments on degrees of similarity of 2 BICIs derived from different sources

## BICI Development Issues	

- Granularity
- How broad
- How deep
- Logical vs. physical structure of book
- Chapter, section, etc.
- Location (page)
- Consistent with SICI

## BICI Development Issues

- Focus on the ISBN
- Identifier vs. meaning
- Matching and uniqueness
- Character set -- Unicode

## Current BICI Structure

- 3 Segments (Item, Component, Control)
- Control segment manages processing
- Code Structure Identifier data element specifies coding structure
- Focus on ISBN
- Logical and physical structure

## Current BICI Structure

- Item Segment
- ISBN
- Chronology
- Item enumeration
- Component Segment
- Component enumeration
- Title code
- Location (e.g., pagination) or other numbering schema
- Control Segment
- Code Structure Identifier (CSI)
- Component Type Identifier (CTI)
- Medium/Format Identifier (MFI)
- Standard Version Number (SVN)
- Check Character

## Current BICI Example

- Chapter 10: “English as a World Language” in *The English Language: A Historical Introduction*, 1993 pp. 234-261 ISBN 0-521-41620-5
- BICI: 0521416205(1993)(10;EAAWL;234-261)2.2.TX;1-1

## BICI Component Types	

- 0	Whole item
- 1	Front matter
- 2	Main text subdivision (parts, chapters, sections, acts, etc.)
- 3	Discrete object within a book (abstracts, tables, figures, etc.)
- 4	Back matter (index, appendices, references, bibliographies)
- 5	Supplementary materials (maps, disks, erratum, etc.)

## BICI Applications

- Abstracting and indexing services
- Document delivery services
- Coursepack producers
- Library reserve rooms
- Rights management agencies
- DOI system
- Publisher delivery systems
- E-books

## BICI Community Review

- Changed <> to ()
- Include both logical and physical in component segment
- Use ; as delimiter between elements
- Restructure title code rules
- More e-book examples

## BICI Future Development

- Final draft (committee draft 10) to be vetted by committee
- NISO draft out this summer
- Vote by NISO membership by fall
- Resolution of any negatives
- Publication by end of 2000
